Why PDF Tools
-
Private by design
Everything runs on your device. There is no server to upload to, no account to create and no analytics script watching you.
-
Original quality
Pages are copied object-for-object and text is embedded natively. Vectors, images and dimensions are preserved exactly.
-
Fast and free
No queues, no watermarks and no page limits. Files are processed instantly in memory and downloaded straight back to you.
Frequently asked questions
-
Are my files uploaded anywhere?
No. Every tool runs entirely in your browser using JavaScript. Your PDFs are read from your device, processed in memory and downloaded back to you. There is no server, no account and no analytics.
-
Is there a file size limit?
There is no fixed limit. The only constraint is your browser’s available memory, so very large files work best on a desktop browser.
-
Does merging or editing reduce quality?
No. Pages are copied object-for-object and text or images are embedded natively into the original PDF. Nothing is rasterised or recompressed.
-
Which fonts can I use in the editor?
Helvetica, Times and Courier work fully offline. You can also pick from more than 1,900 Google Fonts; the font file is only fetched from Google when you choose one, and it is embedded into your PDF.
-
Can I open a password-protected PDF?
Not yet. Remove the password first, for example by printing the file to a new PDF, then merge or edit the unprotected copy.
