Free Online PDF Tools That Keep Your Files on Your Device
PDF is how documents travel: contracts, invoices, bank statements, scans of IDs and certificates. That is exactly why uploading them to an unknown server to merge two files or remove a page is a poor trade. The PDF tools here do the work in your browser, so the document never leaves your device.
What is in this category
| Tool | What it does | Reach for it when |
|---|---|---|
| PDF Tools | Merges PDFs, splits them by page or range, extracts, deletes, rotates and reorders pages with thumbnails | A document has to be combined, cut into parts, cleaned of blank pages or turned the right way up |
| PDF Converter | Turns PDF pages into JPG, PNG or WebP images at 72 to 300 dpi, or extracts the text | A page has to be posted, attached or put in a slide as an image, or its words reused |
| PDF Compressor | Makes a PDF smaller by recompressing its pictures while the text stays sharp, or by turning pages into images; can aim for a size such as 1 MB | A file is too large for an email or an upload form |
Quick links: merge PDF, split PDF, extract pages, delete pages, rotate PDF, PDF to JPG, PDF to PNG, PDF to text, reduce PDF size, compress PDF to 1 MB and compress PDF to 100 KB. For turning images into a PDF, see image to PDF, JPG to PDF and PNG to PDF in the image tools; for a PDF stored as text, Base64 to PDF.
Why in the browser
A PDF can be read and rewritten without a server. The tools here use pdf.js, the PDF engine inside Firefox, to draw page previews, and pdf-lib to write the new file. Both are open-source libraries that run as JavaScript on your device, which is why there is no upload wait, no file-size tier and no copy of your document on someone else's disk.
What changes and what does not
- Pages are copied, not redrawn. When you merge, split or reorder, text stays selectable, fonts and images are not re-compressed, and each page keeps its own size. Only the converter draws pages as images, at the resolution you choose.
- Compression changes pictures, not text. The compressor recompresses the images inside a PDF and leaves text and vector drawings as they are, unless you choose its Maximum mode, which turns pages into images.
- Rotation is a page setting. Turning a page changes a number in the file, so it costs no quality.
- The original is never touched. Every action produces a new file for you to download.
- Document-wide extras are dropped. The bookmark list and interactive form fields do not carry over into the new file.
Protected PDFs
Files locked with a password or with restrictions against editing cannot be changed here. That is deliberate: working around a protection you did not set is not something a tool should do silently. If the file is yours, remove the protection in the program that created it and try again.
Tips
- Number files before merging (01-, 02-, …) so they arrive in the right order.
- Delete blank scan pages before you merge; the result is smaller and easier to read.
- For a very large scan, use a computer rather than a phone: the whole file is held in memory while you work.
