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
What is Gmail's attachment size limit?⌄
Gmail allows attachments up to 25MB. Files larger than that are automatically sent as a Google Drive link instead of an attachment.
How do I get my PDF under 25MB for Gmail?⌄
Upload the file, choose "Balanced" or "Extreme" compression, and download the smaller version. Most PDFs drop well under 25MB in one pass.
Why is my PDF too large to attach?⌄
Large PDFs usually contain high-resolution scans or images. Compression re-encodes those images to a smaller size, dramatically reducing the total.
Will compressing hurt readability for the recipient?⌄
No. "Balanced" compression keeps text sharp and images clear, which is ideal for most email attachments.
Is it safe to compress sensitive emails attachments?⌄
Yes. Compression runs in your browser, so invoices, contracts, and statements never get uploaded.
