Crop PDF Files Without Uploading — Why It Matters for Privacy
Most online PDF tools require uploading your documents to external servers. This can be risky when dealing with confidential files such as contracts, business reports, financial files, and personal records.
CleanPDF solves this problem by processing PDFs locally in your browser using modern web technology (PDF-lib). Your files are never stored, transferred, or accessed by any third party.

Crop PDF Files on Any Device — Desktop, iPhone, or Android
CleanPDF works on all modern devices without any app installation.
Crop PDF on iPhone or iPad (Free, No App Needed)
Open CleanPDF in Safari on iOS. Tap the upload area, choose your PDF from Files, drag on the page preview to select your crop area, and tap Crop & Download. The finished file saves to your Downloads folder instantly.
Crop PDF on Android (Chrome or Firefox)
Use Chrome or Firefox on Android to access CleanPDF. Select a PDF from Google Drive or device storage, draw your selection with your finger, and download the cropped result — all processed on your phone.
Crop PDF on Mac or Windows
Any desktop browser works — Chrome, Firefox, Edge, or Safari on macOS. For very large files, desktop browsers have more available memory than mobile, so cropping large documents is faster and more reliable on a laptop or PC.
When Would You Need to Crop a PDF?

Extract just a chart, table, or paragraph from a page for use in a presentation or report.
Receipts & Forms
Crop a long receipt or form down to just the relevant section before filing or sharing.

Frequently Asked Questions
Everything you need to know about cropping PDF files online for free
General & Privacy
Can I crop PDF files for free?
Yes. CleanPDF lets you crop PDF pages completely free, with no limits, watermarks, or registration.
Is it safe to crop PDF files online?
Yes. Our tool processes files directly inside your browser using local JavaScript. Your documents never leave your device.
Does CleanPDF comply with GDPR when cropping PDFs?
Yes. Because no file content is ever transmitted to our servers, there is nothing to store, process, or retain — making it suitable for EU businesses, healthcare, and legal professionals.
How It Works
Will cropping actually delete the hidden content, or just hide it?
CleanPDF resizes the page itself to your selected area, so anything outside the selection is genuinely removed from the page — not just visually hidden by a viewer setting.
Can I crop every page of a multi-page PDF at once?
Yes. Draw your selection on one page, then enable "Apply to all pages" before downloading.
Can I crop a PDF on mobile?
Yes. The tool works on Android (Chrome/Firefox) and iPhone/iPad (Safari) — just drag your finger to select the crop area.
Files & Compatibility
Is there a file size limit for cropping?
CleanPDF imposes no file size limit of its own. The practical limit depends on your browser and device memory.
Can I crop a password-protected PDF?
CleanPDF cannot crop PDFs that require a password to open. Remove the password first using our Unlock PDF tool, then crop the unlocked file.
Will cropping reduce my file size?
Cropping resizes the visible page rather than recompressing content, so file size and quality stay essentially the same.
