Compress PDF Without Losing Quality
This page opens the compressor at the Light level, made for when you want to reduce PDF size but keep quality: text and vector drawings stay exactly as they are, low-color graphics like logos and charts stay lossless, and only photos above roughly 220 DPI are resampled. The saving is smaller than with stronger levels, but in most documents the result looks the same on screen and in print.

How to compress a PDF and keep its quality
- 1Select the PDF you want to make lighter.
- 2Keep the preset Light level and leave the target size empty, so the tool doesn't push quality down to hit a number.
- 3Press Compress PDF.
- 4Compare the before and after size on the result card, open the file to check it, then download it.
Good to know
- Savings depend on the images. A PDF of high-resolution photos shrinks a lot; a text-only report barely changes.
- If the result is still too big, try Recommended next. Documents stay readable and much lighter, but look over the photos afterwards.
- Don't compress the same file again and again: each pass can soften photos a little more. Start from the original every time.
- For print jobs, Light is the safe choice. For email and web uploads, Recommended is usually enough.
Frequently asked questions
Is this compression completely lossless?
Not completely. Text, fonts and vector graphics aren't changed, but photos may be resampled and re-encoded at high quality. In most documents the difference is hard to see.
Why did my file barely get smaller?
If the PDF is mostly text or its images are already optimized, there's little to remove without hurting quality. The tool never gives you a file bigger than the original.
Is it free?
Yes, 3 times a day per tool with no sign-up. The file is uploaded encrypted and deleted right after processing.
