FAQ
Will compression be lossless?
No. Browser compression re-renders pages as images for size reduction. Text-only PDFs may barely shrink. Image-heavy and scanned PDFs see the best results.
Do you upload my PDF?
No. Compression happens locally in your browser.
Which strength should I use?
Start with Balanced. Use Strong for scanned documents when you accept more quality loss.
Why did my file size barely change?
Already-optimized or text-only PDFs often have little room to shrink without server-side tools.
