One PDF — any size, no upload
🔒 Files never leave your device — everything runs in your browser.
Scans with wide dead margins, slides exported with padding, ebooks whose text swims in white space: cropping fixes them all at once. The first page renders as a live preview — drag the box to frame what should remain, and the same relative trim applies to every page in the document, so a hundred-page scan is cropped in one move. Text stays vector-sharp and selectable; nothing is re-rendered.
One honest warning, because it matters: cropping changes what a page shows, not what the file contains. Content outside the box is hidden, not deleted — anyone can restore it with another tool, so never use cropping to redact sensitive information. For trimming margins and reframing pages it's exactly right, and it all happens in your browser: the document never leaves your device.

Frequently asked questions
Does the crop apply to all pages?
Yes — you frame the first page and the same relative crop applies to every page, whatever its size. Mixed portrait and landscape documents each keep their own proportions; the trim is percentage-based, like margins.
Does cropping make the file smaller?
No — the hidden content is still stored in the file, so the size barely changes. To shrink the file, use Compress PDF, which re-encodes the images inside while leaving text sharp.
Can I use this to black out sensitive information?
No, and this matters: cropping only hides content — the data remains in the file and can be restored by anyone with a PDF editor. Genuine redaction requires removing the content itself, which this tool deliberately does not claim to do.
Will the text stay selectable after cropping?
Yes — cropping adjusts the page's visible area without touching the content streams. Text remains sharp, selectable, and searchable, exactly as before.
Is my file uploaded to a server?
No. ConvertUno runs entirely in your browser on your own device. Your file never leaves your computer or phone — there is no upload at all.
Is it really free, with no watermark?
Yes. Processing happens on your device, so serving you costs us almost nothing — no watermark, no account, no file-size limit, no daily quota.
