Frequently asked questions
- Why compress to 1 MB?
- 1 MB is a common email-friendly size. It keeps multi-page and scanned documents looking good while staying small enough to send or upload.
- Can it handle large, multi-page scans?
- Yes. Compression runs in a background worker so big files don't freeze the tab, and scanned pages shrink the most.
- Do my files get uploaded?
- No — everything runs in your browser. Your PDF never leaves your device.
Make big documents emailable at 1 MB
1 MB is the classic “email-friendly” size. It's small enough to attach to almost any message or drop into a shared drive, yet generous enough that long, image-heavy, or scanned documents keep most of their quality. When a PDF is several megabytes because of high-resolution scans, compressing to 1 MB usually makes it practical to send without any visible loss for on-screen reading.
Built for large, multi-page scans
This is the target to reach for when a whole scanned booklet or a picture-filled report has ballooned in size. HivePDF runs the compression in a background worker, so even a big file with many pages won't freeze your browser, and it downscales the images that are inflating the file while leaving genuine text selectable.
