Why pick Convertify for this?
Files stay on device
Convertify processes everything in your browser using JavaScript. Your file is never uploaded — confirm with DevTools → Network. That makes this safe for sensitive material like contracts, IDs, and financial documents.
No upload wait
Because nothing uploads, processing starts the instant you click. For typical files (under 50 MB) the whole job finishes in seconds — no progress bar, no queueing behind other users.
No daily quota
Free without limits, including no "3 conversions per day" cap that competing services impose. Run as many compress pdf jobs as you need.
No watermark
Your output is clean — no Convertify branding, no metadata stamp. Same as if you'd run a paid desktop app.

Frequently asked questions
How do I compress a PDF to under 500KB?⌄
Upload the file and choose "Balanced" compression first. If it's still above 500KB, switch to "Extreme" and re-check the size before downloading.
Why do upload forms require 500KB?⌄
Many application and registration portals set a 500KB cap to keep storage manageable and uploads quick, especially for multi-document submissions.
Can a multi-page PDF reach 500KB?⌄
Yes, in most cases. Text-heavy and lightly scanned documents compress well under 500KB; very image-heavy files may need fewer pages.
Will quality suffer at 500KB?⌄
Text remains readable, and 500KB is roomy enough that most documents look clean. Check the preview if your file has detailed photos.
Is my document uploaded?⌄
No. Compression runs in your browser, so your files stay private.
