UPSC certificates and one-to-two page documents usually stop at 100KB. Crafex compresses them in your browser — client-side WASM, zero-server, 100% private — with the Saved % badge confirming you cleared the cap.
100KB is a common cap for UPSC certificate and declaration uploads.

Single or multiple PDFs • No file size limit • No signup
Tip: For 100KB, try Medium first — switch to High if still over limit. All processing stays in your browser.
Medium keeps fine print on certificates readable while fitting under 100KB.
Extract only required pages if the file is a longer scan bundle.
Re-run on High if the validator rejects — you keep full quality control.
