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 get a PDF under 1MB?

Upload your file and select a compression level. 1MB is an easy target for most documents — "Balanced" usually gets you there while keeping quality high.

Is 1MB good quality for a PDF?

Yes. 1MB allows sharp text and clear images for most multi-page documents, making it a good balance between size and clarity.

Why do portals ask for under 1MB?

A 1MB limit keeps uploads fast and storage efficient while still allowing reasonable document quality, so it's common for resumes and forms.

Can I compress a scanned PDF to 1MB?

Usually yes. Scans compress significantly because their images carry most of the weight, often dropping below 1MB easily.

Is the compression private?

Yes. Your PDF is compressed locally in your browser and never uploaded.
