About Weesize

Weesize is a free, open-source tool that compresses photos, signatures and PDFs to an exact file size in your browser, without uploading files.

Weesize is built for students and job applicants resizing photos, signatures and PDFs for online forms, as well as anyone who wants private file compression without uploading files to remote servers.

How is Weesize different?

Weesize does one job better than anyone: gets any photo, signature or PDF to the exact size a form needs. It is not a 100-tool PDF suite; for full PDF page editing and document creation, we warmly recommend BentoPDF. Weesize focuses entirely on exact size targeting, background cleaning, and fast on-device performance.

All processing runs directly in your browser using modern WebAssembly and JavaScript engines under the permissive MIT license. Once the web application loads, you can turn off Wi-Fi or disconnect from the internet completely and continue using all features offline.

Connect with our project on GitHub (https://github.com/Ansochacko/weesize) and Instagram (https://www.instagram.com/weesize).

About Weesize is processed entirely on your device. Your original file remains untouched, and nothing is ever uploaded to a server or saved in the cloud.

Key Principles

  • 100% on-device processing via browser WebAssembly and Web APIs.
  • Open source repository on GitHub under the MIT license.
  • Zero server uploads, zero sign-ups, zero tracking scripts, and zero ads.
