APITemplate.io vs Imejis.io: Which API Fits? [2026]

APITemplate.io and Imejis.io look like competitors on paper. Both generate images through an API. Both have template editors. Both offer regional endpoints across four continents. But once you dig in, you realize they solve different problems.

APITemplate.io is a PDF-first platform. Its HTML-to-PDF engine is the real product. Image generation is a side feature they added later. Imejis.io is the opposite, built from scratch for image generation, with no PDF engine at all.

I've tested both APIs, built templates in both editors, and run real workloads through each. Here's exactly how they compare and which one makes sense for your project.

The core difference pdf first vs image firstThe Core Difference: PDF-First vs Image-First

APITemplate.io's founding story is about documents. HTML-to-PDF conversion was the original product, and it shows. The PDF rendering engine is genuinely excellent, probably the best you'll find through an API today. When they added image generation, it arrived as a secondary feature built on top of existing infrastructure.

Imejis.io started with images and stayed there. Every feature (the editor, the API response format, the integrations, the storage model) was designed around one thing: generating images from templates as quickly and cheaply as possible.

Why does this matter? Because when a platform treats something as a secondary feature, you feel it everywhere. The editor is less polished. The pricing bundles in capabilities you don't need. The template management has limits that exist to protect a system designed for a different workload.

So before comparing features line by line, ask yourself: do I need PDFs, images, or both?

The mathThe Math

At the entry paid tier, APITemplate charges $29 for 1,500 credits. That works out to about $0.019 per image. Imejis charges $14.99 for 1,000 credits, roughly $0.015 per image. Imejis is about 21% cheaper per image right out of the gate.

But the gap widens at scale. Need 5,000+ images a month? APITemplate's Standard plan charges $69 for 5,000 credits. Imejis.io's Pro plan is $24.99 for 10,000 credits, double the volume at 64% less cost.

And then there's the template limit problem. APITemplate's $29 Starter plan caps you at 15 templates. If your marketing team runs more than 15 campaigns or ad variations, you're forced up to Standard at $69/month, not because you need more credits, but because you ran out of template slots. With Imejis, templates are unlimited on every plan.

Free tierFree Tier

Both platforms offer permanent free tiers, which is good. APITemplate gives you 50 credits/month with a hard cap of 3 templates. Imejis gives you 100 credits/month with unlimited templates and no watermarks.

That's double the credits and no artificial template ceiling. For prototyping or low-volume projects, the difference is real.

Template editorTemplate Editor

This is where you feel the PDF-first vs image-first split most clearly.

Apitemplateios editorAPITemplate.io's Editor

APITemplate has a drag-and-drop editor for image templates. It handles basic layouts fine: text over a background, a product shot with a price overlay, simple social graphics. But the interface feels dated. There's no built-in stock photo library. Layer management is minimal. The design controls are limited compared to what modern editors offer.

Where APITemplate's editor shines is on the PDF side. Their HTML/CSS template approach gives developers full control over layout, typography, and page structure. If you're building invoices, certificates, or reports, the code-based approach is actually quite powerful.

Imejisios editorImejis.io's Editor

Imejis built its editor to feel like Canva. Real-time preview, drag-and-drop positioning, professional layer management, and a built-in Unsplash integration so you can pull stock photos into templates without leaving the editor.

The gap shows up most when non-technical team members need to create templates. A marketing manager can open Imejis's editor and build a social media template in minutes. The same person would struggle with APITemplate's image editor and likely give up entirely on the HTML/CSS PDF templates.

Api design developer experienceAPI Design & Developer Experience

Here's something both platforms get right: regional endpoints. APITemplate runs in the US, EU, Singapore, and Australia. Imejis runs in the US, EU (Germany), Singapore, and Australia. Having local endpoints reduces latency for global teams, and it's surprisingly rare in this space. Most image generation APIs still run from a single US region.

Apitemplateios apiAPITemplate.io's API

APITemplate's API serves both PDF and image generation, so the documentation is broader. You send JSON data mapped to template layers and get back JPEG or PNG output. The API supports sync and async modes, with webhooks for async jobs.

A nice bonus: APITemplate includes QR code and barcode generation endpoints. If you're building product labels, event tickets, or shipping documents, that's a useful feature you won't find in most image APIs. For related use cases, see our guide on invoice and receipt image generation.

Imejisios apiImejis.io's API

Imejis keeps it minimal. One endpoint. Send your template ID and the dynamic data as JSON, get the image URL back in the response. No polling, no webhooks, no async complexity. For most image generation workflows (social posts, ad creatives, product images), this is exactly what you want.

The integration ecosystem is wider too. Imejis connects to Zapier, Make, n8n, Airtable, Bubble.io, Pipedream, and more. APITemplate covers Zapier, Make, and Airtable but misses the rest.

And there's one feature that's unique to Imejis: public shareable links. You can turn any template into a simple web form. Share the link with a teammate, and they can generate images by filling out fields, no API key, no code, no technical knowledge. For marketing teams with mixed skill levels, it removes a real bottleneck.

Template limits the quiet bottleneckTemplate Limits: The Quiet Bottleneck

This deserves its own section because it's the kind of restriction you don't notice until it bites you.

APITemplate.io enforces strict template limits at every tier:

• Free: 3 templates
• Starter ($29/month): 15 templates
• Standard ($69/month): 50 templates
• Pro ($149/month): 100 templates

Think about what 15 templates actually means in practice. You might have templates for Instagram posts, Facebook ads, Twitter cards, LinkedIn banners, email headers, product images, and blog thumbnails. That's 7 template types. Now add a few variations (dark mode, light mode, seasonal) and you're at 15 before your second month.

At that point, you're choosing between deleting old templates or upgrading to $69/month. Not because you need more credits. Because you need more template slots.

Imejis.io doesn't have template limits. Not on the free plan, not on any paid plan. Create as many templates as your workflow demands. This alone can save you $40/month if it prevents an unnecessary tier upgrade on APITemplate.

Image retention storageImage Retention & Storage

Both platforms offer permanent image retention on paid plans, meaning your generated images don't expire after a set period. This matters if you're generating images for long-lived content like blog posts, product pages, or evergreen social media.

APITemplate stores images permanently on paid plans. Imejis stores all images permanently, including those generated on the free tier. If you're running a low-volume project and want images to stick around without paying, Imejis has the edge.

Where apitemplateio winsWhere APITemplate.io Wins

I want to be fair here. APITemplate.io does several things that Imejis simply doesn't offer:

• HTML-to-PDF generation. This is APITemplate's flagship, and it's best-in-class. If you need to generate invoices, reports, certificates, or contracts from templates, APITemplate is the tool. Imejis doesn't do PDFs at all.
• QR code and barcode generation. Built-in endpoints for QR codes and barcodes. Useful for product labels, event tickets, and shipping.
• Code-based PDF templates. The HTML/CSS approach gives developers pixel-perfect control over document layouts. If you're comfortable writing code, the flexibility is impressive.
• Combined PDF + image in one platform. If your needs are split across documents and images (and your image needs are simple), one API key and one billing relationship has value.

Where imejisio winsWhere Imejis.io Wins

For image-specific work, Imejis comes out ahead across several dimensions:

• Better editor. The Canva-like drag-and-drop editor is more modern, more capable, and more accessible to non-technical users.
• More generous free tier. 100 credits vs 50. Unlimited templates vs 3. No watermarks.
• Lower pricing at every tier. $14.99 vs $29 at entry. $24.99 for 10,000 credits vs $69 for 5,000. That's real money saved over a year.
• No template limits. Ever. On any plan. This removes a frustrating and expensive bottleneck.
• Built-in Unsplash photos. Stock images directly in the editor. No separate subscriptions or manual uploads.
• Public shareable links. Let non-technical team members generate images through a simple form.
• More integrations. Zapier, Make, n8n, Airtable, Bubble.io, Pipedream. APITemplate covers fewer platforms.

Who should pick apitemplateioWho Should Pick APITemplate.io?

APITemplate is the right choice if:

• PDF generation is your primary need. Invoices, reports, certificates, legal documents. This is where APITemplate is unmatched.
• You need QR codes or barcodes. Product labels, shipping documents, event tickets.
• You're a developer who prefers HTML/CSS templates. The code-based approach for PDFs is genuinely powerful.
• Your image needs are basic. If you only generate a handful of simple image types alongside your PDF workload, keeping everything in one platform might be worth the premium.

Who should pick imejisioWho Should Pick Imejis.io?

Imejis.io makes more sense if:

• Image generation is your main workflow. Social media graphics, ad creatives, marketing banners, product images, blog thumbnails.
• You need more than 15 templates. Which most active marketing teams do within their first few weeks.
• Your team includes non-developers. The visual editor and public links make Imejis accessible to everyone.
• Budget matters. You'll save 48% at entry level and 64% at the 5,000-credit tier compared to APITemplate.
• You want built-in stock photos. The Unsplash integration keeps image quality high without extra subscriptions.
• You need broad integrations. n8n, Bubble.io, and Pipedream support means more automation options.

Can you use bothCan You Use Both?

Yes. And honestly, this might be the smartest approach for teams that need both PDFs and images.

The setup I've seen work well: APITemplate.io handles all PDF generation (invoices, receipts, reports, contracts) while Imejis.io handles all image work (marketing banners, social graphics, product images, ad creatives). Each tool does what it was designed for. No compromises.

The APIs are independent, so there's no conflict. You'd have two API keys and two billing accounts, but you'd also have two tools each operating in their sweet spot instead of one tool doing a mediocre job at half its workload.

If your PDF and image workflows are both small, a single platform might make sense to keep things simple. But if either side is growing, splitting them gives you better quality and, in most cases, lower total cost.

The bottom lineThe Bottom Line

APITemplate.io and Imejis.io aren't fighting over the same territory. One is a PDF tool that happens to generate images. The other is an image tool that doesn't pretend to do PDFs.

If you need PDFs, pick APITemplate. The HTML-to-PDF engine is the best in the market, and nothing else comes close.

If you need images, pick Imejis. You'll get a better editor, unlimited templates, a more generous free tier, wider integrations, and prices that are 48-64% lower depending on your volume. At $14.99/month vs $29/month for entry plans, and $24.99 for 10,000 credits vs $69 for 5,000, the savings are hard to ignore.

And if you need both? Run them side by side. Best PDF engine plus best image platform. No compromises, no forced upgrades, no template limits holding you back.
