Question 1

Does my PDF get uploaded anywhere?

Accepted Answer

No. The compression runs in your browser tab. We never see the file, and our servers never receive it.

Question 2

Is it free? How do you pay for it?

Accepted Answer

Yes, free for everyone. The site is funded by ads shown around the tool (never on top of your file content).

Question 3

Will my PDF lose quality?

Accepted Answer

For compression, it depends on the preset. Light keeps everything as is. Recommended trades a bit of sharpness for size. Extreme makes pages noticeably softer. Merge keeps original page quality.

Question 4

How big a file can I process?

Accepted Answer

Compress supports up to 100 MB per file. Merge supports up to 200 MB total per batch. Bigger jobs can be slow on older devices.

Question 5

Does it work on encrypted PDFs?

Accepted Answer

Not yet. Remove the password first in your PDF reader, then try here.

Question 6

Which browsers are supported?

Accepted Answer

Modern Chrome, Firefox, Edge and Safari (16.4+). Older browsers without OffscreenCanvas won't work.

Question 7

Why is there no account or login?

Accepted Answer

There's nothing to save. Files don't leave your device, so there's no history, no library, no cloud.

Question 8

What else are you adding?

Accepted Answer

Split, rotate, watermark, and image-to-PDF are next. Same client-side approach, same privacy rules.
