Frequently Asked Questions
Yes. All processing happens in your browser. Your PDF is never uploaded to any server.
No. Cropping only hides parts of the page - it doesn't re-encode or compress the content. Quality stays exactly the same.
Yes. In the editor, choose "All Pages" to apply the same crop to every page, or "Current Page" to crop only the page you're previewing. You can also enter a custom page range (e.g., 1, 3, 5-8) for precise control.
Preset margins let you quickly crop 0.5 inches or 1 inch from all sides of every page with one click. For more control, drag the crop handles manually in the visual editor.
Limits adapt to your device - the dropzone shows your exact per-file limit. Larger files may take longer to load in the crop editor.
The crop sets a new CropBox which hides content outside the crop area. The hidden data is still in the file - for a smaller file, pair with Compress PDF after cropping.
Yes. Use the preset margins or manually drag the crop box to frame the scanned content precisely. The visual editor lets you see exactly what will be cropped.
Yes. Open this page in Chrome or Safari on Android or iPhone — no app needed. Upload from your files, use preset margins or drag the crop box with touch, and download the cropped PDF. The same editor works in any desktop browser on Windows, Mac, or Chromebook.
Tap the 0.5 inch or 1 inch preset to trim equal white margins from all sides at once, or drag the crop box for uneven borders. If only some pages need trimming, enter a page range first.
No. You set the crop area yourself with a preset margin or by dragging the visual crop box, so text near the edge never gets cut automatically.
