Question 1

Do my PDFs get uploaded to a server?

Accepted Answer

No. mypdf.space runs every tool in your browser. File bytes stay on your device — we do not operate a PDF upload API.

Question 2

Is it free? Will you add a watermark?

Accepted Answer

Yes — free to use, no account, and no watermark on exports.

Question 3

Can I use the tools offline?

Accepted Answer

After you install mypdf as an app (or once assets are cached), most tools keep working without a network.

Question 4

If I switch tools, do I have to re-upload?

Accepted Answer

Usually no. After you open a PDF, mypdf keeps it in a browser session so other tools can continue with that same file. Closing the tab clears it — nothing is stored on our servers.

Question 5

Are there file size limits?

Accepted Answer

There is no server quota, but your browser’s memory is the limit. Very large or image-heavy PDFs can feel slow or fail on low-RAM devices.

Question 6

Does Compress keep selectable text?

Accepted Answer

Yes by default — Keep text preserves selectable text. Max shrink rasterizes pages and restores a searchable overlay when text exists.

Question 7

How do I prepare a confidential PDF?

Accepted Answer

Use Privacy scanner, then Auto-redact PII, or run Confidential Send for scan/redact, strip metadata, CONFIDENTIAL watermark, and encrypt in one local pass. Always review every page before sharing.

Question 8

Is redaction permanent?

Accepted Answer

Yes. After you apply redaction, covered regions are flattened to black in the downloaded file and are not recoverable from that export. Auto-redact PII only catches common patterns.

Question 9

Is Sign PDF a legal digital certificate?

Accepted Answer

No. Sign PDF places an image of your signature. It is not a cryptographic certificate.

Question 10

Do you use analytics?

Accepted Answer

Yes — anonymous page-view metrics via Google Analytics. Analytics never receives your PDF files or passwords. See the Privacy page for details.

Question 11

How do I contact support?

Accepted Answer

Use the Contact link on mypdf.space — it opens your email app so you can reach the team.
