Add a PDF to trim page margins without uploading it.
Your PDF stays on this device. Cropping runs locally in your browser.
A PDF cropper changes the visible boundary of each page so wide margins, scanner borders, or unwanted edge content no longer appear. Add a PDF, enter the top, right, bottom, and left margins in millimetres, choose the pages, preview the kept area, and download the result without uploading your file.
Choose a local PDF or drop it into the workspace. The browser reads its page count and geometry.
Enter how many millimetres to trim from the top, right, bottom, and left visible edges. Check the shaded preview.
Apply the same crop to every page or enter individual pages and ranges such as 1, 3-5.
Crop the PDF, review the summary, and save the new file to your device.
Crop one page range or the whole document. The tool reads each page's existing CropBox and applies your margins relative to the edges you see, including rotated pages. It preserves the document's text, vectors, links, and image quality because it changes page geometry instead of rasterizing the PDF.
Processing happens locally in your browser. Files up to 100 MB and 1,000 pages are supported, subject to the memory available on your device.
No. The PDF is opened, previewed, and cropped locally by code running in your browser. The file is not sent to CanDoYa for processing. Your browser only creates a new downloadable PDF on your device.
Yes. You can crop PDF pages without creating an account, adding a watermark, or paying for a download. The practical limits are 100 MB and 1,000 pages per file, plus the memory available to your browser.
No. Standard PDF cropping sets the visible CropBox and usually leaves content outside that boundary in the document. Do not use cropping to conceal private text or images. Use a proper PDF redaction workflow when information must be removed.
Yes. Choose Selected pages and enter page numbers or ascending ranges separated by commas, such as 1, 3-5, 8. The chosen pages receive the margins while every other page keeps its current crop boundary.
No raster conversion is used, so text, vector artwork, images, links, and existing page content retain their original quality. The output changes only the visible page boundary for the pages you select.
The margin labels always match the top, right, bottom, and left edges shown by a PDF viewer. The tool maps those visible edges back to the page's stored coordinates, so a 90-degree rotated page crops in the direction you expect.
Yes, but one margin set is applied to every selected page. The tool checks each selected page before processing and stops if the margins would leave any page too narrow or too short. Preview representative pages in mixed-size documents first.
