Compress a PDF without signing up
The signup wall on most PDF sites exists for their funnel, not for your file.
You don't need an account. GigAI's PDF compressor works the moment the page loads: drop the file, download the result. In our published benchmark a 6.6 MB image-heavy PDF became 90 KB in 2.2 seconds - processed in your browser, never uploaded, no daily cap.
3 tools for this
Each one is free, private and runs in your browser. No sign-up, no watermark.
Compress PDF
Shrink a PDF's file size right in your browser. Pick a compression level, see exactly how much you saved, and download. No uploads, no watermark.
GigAI Fit
Tell GigAI the maximum size you need and it works out how to get there, images, PDFs, video and audio, all compressed in your browser.
Split PDF
Break one PDF into several smaller files. Split every page out, or carve out custom page ranges. Free, fast and entirely in your browser.
How to fix it
Follow these steps and you'll have it sorted in a couple of minutes.
- 1
Drop the PDF
No email, no trial timer. The compressor is the page.
- 2
Compress
Pages are re-encoded with MozJPEG locally. If compression can't beat the original, you get the original back - never a worse file.
- 3
Download
Repeat as often as you like; there is no daily allowance to run out of.
- Expecting big savings on text-first PDFs - they're already small; scans and image-heavy decks are where 90%+ reductions happen.
- Compressing before merging several files - merge first, compress once.
