Introducing heic.site Pro — PDF Output, File Sharing, and API Access

When I first built heic.site, it did exactly one thing: convert HEIC files to JPG in the browser. No server uploads, no signups, no nonsense. That was the entire product and honestly it was enough.

But people kept asking for more. Could it handle WebP? Can I get a PDF? Can I send the converted files to my coworker without downloading and re-uploading? Can I automate this with an API?

So here’s the deal: the free converter isn’t changing. Unlimited conversions, all the standard image formats, completely private, no ads. That’s staying exactly the way it is. But we’ve added a Pro tier for people who need the extra features.

What’s in Pro

PDF output. Drop any image — HEIC, PNG, JPG, whatever — and get back a properly formatted PDF where the page dimensions match the image. No giant white margins, no letter-size weirdness. Handy for receipts, forms, applications, anything where someone demands a PDF. More on how this works in the PDF conversion deep dive.

File sharing. Convert your images and generate a temporary download link. Send it to anyone — they get a page with individual download buttons and a “Download All as ZIP” option. You pick how long the link lives: 24, 36, or 72 hours. After that we permanently wipe everything — the R2 objects, the database records, all of it. You can also type in an email address and we’ll send the link directly. I wrote up the full breakdown of how sharing works if you want the details.

REST API access. Every Pro account gets a personal API key. Send images programmatically, get converted files back. Good for automating workflows, building integrations, or batch-processing from scripts. Documentation is on the way — we’re finishing up the endpoint this month. If you’re curious about what the API will look like, there’s an early overview here.

Priority support. If something breaks or you need help, Pro users go to the front of the line. Email me directly instead of filing a generic support ticket.

What it costs

$8/month or $60/year (saves you 37%). Cancel anytime from your account page — you keep Pro access through the end of whatever you’ve already paid for.

I went back and forth on pricing for a while. Some competitors charge $5/month for less, others charge $15/month. I landed on $8 because it’s cheap enough that it’s a no-brainer if you convert files regularly, but enough to actually cover the R2 storage and infrastructure costs from the sharing feature.

The yearly plan works out to $5/month, which felt right for people who know they’ll stick around.

Why not make everything free?

I thought about it. The problem is that features like file sharing have real infrastructure costs — every shared file sits on our servers until it expires, and email delivery costs money too. I could slap ads all over the free converter to pay for it, but that felt gross. Nobody wants to look at a sketchy “clean your Mac” ad while they’re trying to convert a photo of their kid.

The current setup lets the free converter stay clean and fast while Pro revenue covers the cost of the features that actually hit our servers.

What’s staying free

I want to be clear about this because I hate bait-and-switch:

  • Unlimited conversions (HEIC, AVIF, WebP, PNG, JPG, GIF, BMP, TIFF → JPG, PNG, WebP, AVIF)
  • Batch conversion with ZIP download
  • Full privacy — everything processes in your browser
  • No ads, no watermarks, no file size limits
  • No account required

If all you need is to turn some HEIC files into JPGs, you will never need to pay us anything. The free tier is the core product. Pro is for power users who want the extras.

How to get it

  1. Go to heic.site and create an account (just email and password)
  2. Hit “Get Pro” on the pricing page
  3. Check out through Stripe (takes 30 seconds)
  4. That’s it — Pro features unlock immediately

You can manage your subscription, download invoices, and cancel from your account page. We use Stripe for billing, so your card info never touches our servers.

What’s coming next

The API endpoint is the big one — should be live within a few weeks. After that, I’m looking at multi-page PDF support (combining several images into one document), server-side conversion for large batches, and a few format-specific features like controlling JPEG compression quality in PDFs.

If you’ve got ideas for what Pro should include, I’d love to hear them. Shoot me a message through the support channel or just reply to any email from us.

Where to start

If you already know which feature you need, these posts go deeper: batch conversion covers the free multi-file workflow, PDF output walks through the page-sizing logic, and file sharing explains the expiry and cleanup setup. Or just head to the pricing page and grab a Pro account — the features unlock right away.
