Trim margins and white space without blurring the text

Crop PDF trims the visible area of PDF pages in your browser. Drag the crop box (or type exact pixel dimensions), then apply it to one page, selected pages, or all of them and download. It keeps text sharp and selectable, and nothing is uploaded to a server.

Load a PDF and you get a three-panel workspace: page thumbnails on the left, a live preview in the centre with a draggable crop box, and controls on the right. Grab any of the eight handles to set the area you want to keep — the darkened overlay shows exactly what will be trimmed away. For exact results, type the X, Y, width, and height in pixels instead, which is ideal for matching strict print margins or a uniform size.

You control where the crop applies: Current Page Only, Selected Pages, or All Pages. That means you can trim a single oversized chart, a batch of scanned sheets, or standardise the whole document in one click. Reset Selection clears the box if you want to start the area over.

Everything runs locally, so contracts, designs, and scans stay on your device. Crucially, cropping here is non-destructive to quality: the tool rewrites the page's crop boundary (the CropBox/MediaBox) rather than turning the page into a flattened image, so your text stays razor-sharp, selectable, and searchable, and vector graphics stay crisp. There's no watermark and no signup, and your original file is left unchanged.

One honest note: cropping hides content outside the box rather than deleting page objects, which is standard PDF behaviour — the visible, printable area is what changes. To shrink the file afterward, use Compress PDF.

When cropping helps

How to crop a PDF

Step 1: Upload your PDF

Drag it into the drop zone or click to browse. The editor opens with thumbnails and a live preview.

Step 2: Set the crop area

Drag the eight handles on the central canvas to frame what you want to keep, or type exact X, Y, Width, Height values in pixels in the controls panel.

Step 3: Choose where it applies

Pick Current Page Only, Selected Pages (tick pages in the thumbnail panel), or All Pages.

Step 4: Download

Click Download Cropped PDF to save the trimmed file.

Realistic example. A scanned report has a 2 cm grey border on every page. Drag the crop box just inside the content on page one, set Apply Crop To: All Pages, and download — every page is trimmed to the same clean area.

Advanced tip. Need identical margins across a document? Use the X/Y/W/H inputs rather than dragging, so every page gets the exact same crop down to the pixel.

Common mistake to avoid. Different page sizes in one file may need different crops — use Current Page Only or Selected Pages for those rather than forcing one crop on all.

Recommendation. Cropping doesn't shrink the file much on its own; run the result through Compress PDF if size matters.

Frequently Asked Questions

How do I crop a PDF?

Upload the PDF, drag the crop box on the central preview to frame the area you want to keep (or type exact pixel values), choose whether to apply it to one page, selected pages, or all, then click Download Cropped PDF. The darkened overlay shows what gets trimmed. It all runs in your browser.

Can I crop by exact pixels or measurements?

Yes. The controls panel has X, Y, Width, and Height inputs in pixels, so instead of dragging you can type precise values. This is the way to match strict print margins or crop every page to exactly the same dimensions.

Can I crop only some pages or all of them?

All three. Under Apply Crop To, choose Current Page Only to crop just the page you're viewing, Selected Pages to crop a chosen subset (tick them in the thumbnail panel), or All Pages to apply one crop across the whole document.

Does cropping reduce quality or blur the text?

No. The tool rewrites the page's crop boundary rather than turning the page into a flattened image, so text stays razor-sharp, selectable, and searchable, and vector graphics stay crisp. This is different from tools that rasterise pages and leave them blurry.

Does cropping delete the content outside the box, or just hide it?

It changes the page's visible, printable area by adjusting the crop boundary — standard PDF behaviour — so content outside the box no longer shows or prints. For everyday use this is exactly what "cropping" means; the result looks and prints as a cleanly trimmed page.

How do I crop different pages with different dimensions?

Crop one page, choose Current Page Only, and download — or crop a group with Selected Pages. Because you can apply a different crop box to different pages or subsets, mixed documents (a wide chart among portrait pages) can each get the right treatment without splitting the file.

Are my files uploaded — is it safe?

No. The cropping happens entirely in your browser, so the PDF never leaves your device or reaches a server. You can even disconnect from the internet after the page loads and keep working. That makes it safe for contracts, designs, and scans; closing the tab clears the file from memory.

Can I crop a PDF on my phone's browser?

Yes. The tool works in any modern browser on iPhone or Android. You can drag the crop handles by touch or type exact values, then download. A larger screen makes precise framing easier, so a laptop is more comfortable for detailed work.

Is it free, with no watermark or signup?

Yes. Cropping is free, the result has no watermark, and there's no account to create. Set your crop, choose the pages, and download a clean file — no paywall before the download.

Does it change my original PDF?

No. The tool produces a new cropped file for you to download; your original stays exactly as it was on your device. Keep the original until you've confirmed the crop is right, since cropping changes the visible area.

How do I remove the white margins specifically?

Drag the crop box inward until it sits at the edge of your content, so the empty margin falls outside the box, then apply to all pages. For consistent margins on every page, type the same X/Y/Width/Height values rather than dragging each page by eye.

My PDF is large — any tips?

Cropping handles large documents; the thumbnail grid and preview may take a moment to render. For a uniform crop across many pages, use the pixel inputs with All Pages rather than dragging page by page. Very large files render more smoothly on a laptop than on an older phone.
