What Crop PDF does

Crop PDF is a browser-based Filozy tool built for this task: Trim the margins. Lossless — only the page box changes. It runs on this device, creates a separate result, and does not require an account or document upload.

Use Crop PDF to choose one PDF, set exact page margins or boxes. Cropping changes the visible page box without re-encoding the objects already inside the document. Filozy starts the document engine only after you choose a file, performs the work inside this tab, and creates a new result for you to save. Your selected document, its filename, and its contents are not sent to Filozy.

How to crop pdf in your browser

  1. Choose one PDFSelect one PDF from the dropzone. Filozy reads it locally and shows the relevant preview or controls before changing anything.
  2. Review the settingsUse the page preview and available options to decide exactly how crop pdf should handle this document.
  3. Create and check the resultRun the tool, review the reported page count, size, or notes, then save the newly created file while keeping the original.

Before you start

  • Decide whether the priority is smaller size, cleaner page edges, compatibility, or visual quality.
  • Keep the original because optimization can intentionally remove editable or unused document data.
  • Open image-heavy or scanned pages at normal reading size so quality changes are easy to notice.

Limits worth knowing

  • Cropping changes the visible page box; it does not securely erase hidden content outside that box. Use Redact when information must be removed.

Frequently asked questions

What is Crop PDF used for?

Crop PDF is a browser-based Filozy tool built for this task: Trim the margins. Lossless — only the page box changes. It runs on this device, creates a separate result, and does not require an account or document upload.

Can I use Crop PDF on a phone or tablet?

Yes. Crop PDF works in a current mobile browser. Complex PDFs can need more memory, so keep the tab open, avoid switching apps during processing, and inspect the result before closing the page.

Does Crop PDF upload my file?

No. The selected file is opened and processed by code running in this browser tab. Document bytes and filenames are not sent to Filozy.

Will this change my original file?

No. Browsers cannot silently overwrite the file you selected. Filozy creates a separate result for you to save or pass to another local tool.

What should I check after using Crop PDF?

Check the visible preview and the result summary. Cropping changes the visible page box without re-encoding the objects already inside the document. Keep the original until the new output has been opened and verified.

Do I need an account or subscription?

No account is required for this browser-side tool. It runs on the device and does not use a document-upload allowance or daily server quota.
