Features

Merge PDF, split PDF and compress PDF in one app

Every tool runs on the device. Open a file on a plane or in a basement and it works exactly the same.

Merge PDF files

Add several PDFs at once, drag them into the order you want, and combine them into a single document.

Delete, reorder and rotate pages

Lay the document out page by page, multi-select to delete pages, drag to reorder, rotate a sideways scan upright.

Sign and fill in forms

Draw your signature once and reuse it forever. Fill text fields, checkboxes, radio buttons and dropdowns, then export.

Scan to PDF with OCR

The camera finds the page edges and straightens the shot. On-device OCR adds a searchable text layer you can copy from.

Split PDF and extract pages

Split by page ranges, every N pages, or one file per page. Or extract only the pages you select as a new document.

Compress to a size you type

Enter the size you are allowed (5 MB for a web form, 2 MB for a portal) and see the estimate before the file is touched.

Unlock and remove passwords

Open a password-protected PDF with its password, then remove the password so the copy you share opens with no prompt.

Annotate and highlight

Add a text box, draw freehand, use the highlighter, drop shapes, sticky notes, images or stamps anywhere on the page.

Watermark and page numbers

Stamp a text or image watermark across every page, and add page numbers with the position and start number you choose.

Images to PDF and back

Turn photos into a PDF at the page size you pick, export pages as JPG or PNG, or save the images embedded in a PDF.

Private by architecture

Your documents never reach a server. There is no server.

Merging, splitting, compressing, signing and OCR all run on your phone. There is no account, so no server ever sees your ID, your payslip or your contract.

How it works

Open or scan

Pick a PDF from your files, or point the camera at a document and let the scanner straighten it.
Edit on the device

Merge, split, compress, sign, annotate or number the pages. Nothing leaves your phone while you work.
Share the result

Export the finished document or the pages as images, and send it straight from the app.

FAQ

Frequently asked questions

Does Kyneto PDF work offline?

Yes. Merging, splitting, compressing, signing, scanning and OCR all run on your device, so the app works the same with no connection at all.

Do I need an account?

No. There is no sign-up and no login. Open the app and start working on a file.

How do I merge PDF files on my phone?

Open Kyneto PDF, choose Merge, add the PDFs you want to combine, drag them into the order you need and export the merged document.

What is the difference between splitting and extracting pages?

Splitting cuts a PDF into several separate files: by page ranges, every N pages, or one file per page. Extracting keeps only the pages you select and saves them as one new document.

Can I remove a password from a PDF?

Yes. Open the protected file with its password, then remove the password so the copy you save and share opens without a prompt. The password never leaves your phone.

Is Kyneto PDF free?

Kyneto PDF is free to download and try. The free tier limits how many documents you can export; a subscription unlocks unlimited exports.
