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, split, rotate, delete, organize, watermark, fill forms and add text keep the original quality. PDF to JPG follows the quality level you pick.

Question 4

How big a file can I process?

Accepted Answer

Most tools support 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

Eleven tools are live right now: compress, merge, split, rotate, delete, extract, organize, PDF to JPG, watermark, fill PDF forms and add text. Next on the list are page numbers, protect/unlock and PDF to Word, built the same way: client-side, private, no sign-up.

Question 9

Is PDFShore GDPR compliant?

Accepted Answer

Compatible by design. Your files never leave your device, so there's no cross-border transfer or storage to disclose. We aren't formally certified, but the architecture itself avoids the data flows the regulation restricts.
