Upload limits
Make a PDF fit a 100KB, 200KB, 500KB, 1MB, or 2MB limit
Upload limits are frustrating because they usually appear at the worst moment. The fix is to start with the target size, then choose the compression level that keeps the document readable.
2026-05-05 - 5 min readStart with the number the portal gives you
If a portal says 2MB, choose a 2MB workflow. If it says 500KB, expect stronger compression and check the preview carefully.
BitePDF shows the original size, output size, and saved percentage so you can tell quickly whether the file is close enough.
Compression is not the only lever
When compression alone is not enough, extract only the required pages, cut extra page ranges, or merge only the pages the portal asks for.
For email and handoff, a file link can also be easier than sending another attachment.
Common targets
The most common targets are 100KB, 200KB, 500KB, 1MB, 2MB, 5MB, and 10MB.
If the file becomes too blurry at one target, try a slightly larger target or remove unnecessary pages before compressing again.
