Will cropping reduce file size?

Slightly — only the visible page box changes; the underlying content stays. Use Compress PDF afterwards for real size reduction.

My Crop PDF job is stuck on "processing".

Refresh the page and try again. Browser-side processing depends on your device's CPU and RAM, so closing other tabs usually helps.

The downloaded file looks different from the preview.

Clear your browser cache and re-run the job. Outdated cached fonts can occasionally cause rendering glitches. If the issue persists, email us a sample to help@pdfwix.com.

Can I undo a Crop PDF operation?

Your original file is never modified — PDFWix always produces a new file. Just discard the new version and start again with the original.
