1.4.0 Minor

Mobile Touch Controls, Big Images, Big PDFs

Use imgfast properly on your phone now. Plus Pro users can work with massive images (32K) and huge PDFs (250MB). Good stuff for photographers, designers, and anyone with a phone.

Three things in this release: mobile finally works like it should, we bumped up the limits for paid users, and PDFs got some love.

Mobile actually works now

We rewrote a bunch of the UI to work properly on phones and tablets. Not just “it fits on screen” - actually usable with touch.

Touch controls in the editor - Pinch to zoom, drag to pan, swipe to navigate. The sliders are touch-friendly now too. Editing images on your phone no longer feels like trying to thread a needle with mittens on.

Layout that makes sense - Buttons are properly sized for fingers, not mouse cursors. Spacing is adjusted so you’re not accidentally tapping the wrong thing. The upload area works with drag-and-drop and tap-to-select.

If you’ve tried imgfast on mobile before and gave up, give it another shot. It’s a different experience now.

Bigger images, bigger PDFs

We got requests from photographers working with panoramas, designers handling infographics, and architects with large scans. The old 4K pixel limit wasn’t cutting it for them.

New dimension limits:

  • Free / Unregistered: 4K (4096px) - same as before
  • Lite: 8K (8192px) - doubled
  • Pro: 32K (32768px) - massive

That 32K limit handles pretty much anything. Stitched panoramas, multi-page scans, giant infographics, exhibition prints. If your image editing software can export it, we can process it.

PDF file sizes:

  • Free / Lite: 20-30MB
  • Pro: 250MB

Pro users can now upload those chunky PDFs - construction documents, architectural plans, print-ready files with embedded fonts. The kind of stuff that used to bounce off the old limit.

PDF rendering improvements

While we were in there, we improved how we handle PDF conversions:

  • Higher resolution rendering when converting PDF pages to images
  • Switched from JPEG to PNG for intermediate processing (no quality loss from recompression)
  • Better handling of complex PDFs with lots of vectors

The output is noticeably sharper, especially on text-heavy documents.

Check the pricing page for the full breakdown. The new limits are live now.

Please note that processing such huge files take a lot of computing resources. For now - our server is fine, there is no need to complicate the pricing and limits, but if we start seeing a lot more use of these extra large images - we may need to introduce separate limits for them.

What’s next

We’re cleaning up some edge cases in the PDF tools and looking at a few feature requests that keep coming up. Nothing huge, just making things more solid.
