About Docomint

Most online file-conversion tools require you to upload a file to someone else's server before you can see the result — even for a simple task like merging two PDFs or converting a JPG. Docomint was built to remove that step wherever it's technically possible: the majority of tools run entirely as code in your own browser, using WebAssembly and native browser APIs, so your file never has to leave your device to be processed.

PDF merging, splitting, and compression; image conversion and resizing; audio conversion; text transforms; and every developer utility on the site run locally in your browser. A small number of tools — Office document conversion, HTML-to-PDF rendering, and PDF/A archiving — depend on server-side engines that can't run in a browser. Those are clearly labeled on their tool page, upload your file only for the duration of that one job, and delete it immediately afterward. The full breakdown of what happens to your files is in the Privacy Policy.

The catalog spans PDF tools (merge, split, compress, convert, edit, sign, protect), image tools (convert, compress, resize), document conversion (Office ↔ PDF, spreadsheets), audio conversion, developer utilities (formatters, encoders, generators), text tools, color tools, and everyday calculators. New tools and improvements ship incrementally, based on what people actually search for and use.

Every tool works without signing up. Creating an account is entirely optional and only unlocks larger file-size limits and saved preferences — it never changes how your files are processed.
