Feemag Tools is a free collection of 33 tools for everyday file chores: compressing photos to an exact size for a form, editing and signing PDFs, converting HEIC photos from an iPhone, cleaning up spreadsheets and more.
Why it exists
Most online converters upload your files to a server you know nothing about. Feemag Tools does the opposite: every tool runs on your own device, inside your browser. Nothing is uploaded, there’s no account, and it keeps working for files you’d rather not share, like ID scans, payslips or contracts.
Who makes it
Feemag Tools is built and maintained by Faheem Riaz, a Senior Flutter Developer and the founder of Feemag, which also runs Persona and ExactKB. You can find Faheem on LinkedIn and GitHub.
How it works
- Images are processed with your browser’s own canvas and image decoders.
- PDFs are read, edited and written with open-source libraries (pdf.js, pdf-lib and QPDF compiled to WebAssembly) that run on your device.
- Spreadsheets are parsed and saved locally with SheetJS.
