Crop PDF — Step-by-Step Guide
Learn how to use Crop PDF: step-by-step instructions, settings, export options, privacy, limits and troubleshooting.
Open Crop PDFStep-by-step instructions
- Choose an unlocked PDF and preview a page.
- Drag the desired visible area or enter left, top, right and bottom margins in points.
- Choose the pages to crop, then export and inspect the result.
Options and output
Margins are measured from the displayed page edges; 72 points equal one inch. The same margins apply to all selected pages, which must each remain at least 12 points wide and high. Cropping changes the visible page box; hidden content is still present and can be recovered. Use Redact PDF for sensitive information.
Compatibility and privacy
Use an unlocked PDF up to 20 MB and 100 source pages. Files and output stay in this browser. Work is not saved after leaving the page. Modifying a digitally signed PDF invalidates its signatures; retain the original. Forms, annotations, bookmarks and document-level interactive features may not survive page rewriting. These tools are not intended to preserve certified or archival conformance.
Review before sharing
Keep the original PDF and check the exported page count, appearance and content before sharing. Browser memory and rendering limitations can prevent a particular PDF from processing; unsupported documents are rejected rather than uploaded elsewhere.
Processing and privacy
Files and entered content are processed on your device in this browser tab. File contents and results are not uploaded to Helphonic or sent to analytics. The page still contacts Helphonic to load its tools, check access and confirm non-content usage information. Work is not saved to your account; download or copy results before leaving or reloading the page.
Access and current limits
Check the tool page for current access, remaining usage and per-operation limits. File count, per-file size, total size and page limits can depend on your access and can change. Device and processor safety limits still apply when usage is unlimited. A paid pass does not necessarily increase every processing limit.
One successful export counts as one operation. Previewing and editing do not use an operation. Daily allowances reset at 00:00 UTC. Downloads of an already-created result do not count again.
If an operation cannot finish
Use a current browser and smaller inputs if the tab runs out of memory. Some tools download a local processing library or model on first use, so an internet connection is needed even though your content stays on the device.
If the tool reports that access or limits changed, review the current policy and run it again. If usage confirmation is uncertain after an interrupted connection, a retry can count as another operation. Download completed work before reloading; this site does not keep a recovery copy.
Check the current limits
Allowances and per-operation limits can change. The Crop PDF page shows the policy that applies to you. Per-operation safety limits still apply when usage is unlimited. See access passes if a tool or extra usage requires paid access.
