Crop PDF Pages
Trim margins and crop PDF pages right in your browser — drag a box, type exact margins, or auto-remove white space. Your file never leaves your device.
Nothing Is Uploaded
Pages are rendered, measured, and re-boxed entirely in your browser. Your document never touches a server — and the tool keeps working offline.
Three Ways to Crop
Drag a box over the page, type exact margins in mm, inches, or points, or let auto-crop find the content for you. Most tools give you only one.
One-Click Auto-Crop
Detect the content on each page and trim the surrounding white space automatically — ideal for scans. No browser-based cropper else offers it.
All, Some, or One Page
Apply the crop to every page, a page range like 2–5, or just the current page. You decide exactly what gets trimmed.
TL;DR: Crop PDF pages right in your browser — drag a box, type exact margins, or auto-trim white space, then apply it to all pages, a range, or one page and download. Cropping changes the visible area by setting a new crop box; the content stays in the file, so it is lossless and reversible. No upload, no signup, no limits.
Why Crop a PDF?
Most PDFs carry more page than you need. A scan arrives with a thick white or grey border and the text floating in the middle; a phone photo of a receipt lands skewed inside an A4 sheet; a shipping label sits in one corner of a full page; a slide deck exported to PDF still has the running header and footer on every page. Cropping cuts the page down to the part that matters, so the content fills the screen, enlarges cleanly on a phone, and prints without wasted ink and paper.
What's different here is where the work happens. The usual online croppers upload your document to a server and promise to delete it later — typically after 30 minutes to a couple of hours. Adobe's online tool even makes you sign in first. This tool crops the PDF entirely on your device: pages are drawn and re-boxed by code running in your browser tab, and the cropped file is saved straight to your downloads. Nothing is sent, so there is nothing to delete.
What Does Cropping a PDF Actually Do?
Cropping a PDF changes each page's visible area by setting a new crop box around the content you want to keep. It hides everything outside that box — it does not re-encode or delete the underlying content, so cropping is lossless and reversible.
That distinction matters. When you crop, the trimmed margins are moved outside the visible area, but they still exist inside the file and can be restored by widening the crop box again. This is exactly how every mainstream tool — including Adobe and Sejda — handles cropping, and it is why cropping never degrades quality: text and vector graphics are untouched, simply framed differently.
It also means cropping is the wrong tool for two adjacent jobs. If you want to change the paper format — say, turn the page into A4 or Letter — that's resizing. If you want a smaller file in megabytes for email, that's compression. Cropping only changes what part of the page is shown.
Three Ways to Crop: Drag, Exact Margins, or Auto-Trim
Different documents call for different ways to choose the crop. This tool gives you all three, and they edit the same selection — start with one and refine with another:
Drag to select
Draw a box directly on the page preview and drag its handles to fine-tune. Everything outside the box is dimmed so you can see exactly what will be kept.
The fastest way when you can judge the crop by eye.
Exact margins
Type how much to trim from the top, right, bottom, and left in millimetres, inches, or points. The selection updates as you type.
Use for print bleed, uniform margins, or trimming a fixed header or footer.
Auto-crop white margins
One click detects the content on the page and trims the surrounding white space for you. It can run per page, so a 30-page scan is squared up in seconds.
The quickest fix for scans and documents with uneven white borders.
Crop a PDF Without Uploading It
Almost every crop tool online — iLovePDF, Smallpdf, Sejda, PDF24, PDF Candy, AvePDF, Adobe — sends your document to a server, then answers the privacy question with a deletion timer: 30 minutes, one hour, two hours. Adobe goes further and requires you to sign in before you can crop a single page. That's a lot of friction, and a lot of trust, for trimming a margin.
This tool skips the trip. The PDF is opened in your browser tab, each page is cropped by JavaScript running on your device, and the result is assembled locally. Load the page, disconnect from the internet, and crop the PDF anyway — that's the whole privacy policy, verifiable in ten seconds.
How to Crop a PDF in 4 Steps
- 1
Open your PDF
Drag and drop the file onto the tool above, or click to browse. The pages load locally in your browser — nothing is sent over the network.
- 2
Choose how to crop
Drag a box on the page, type exact margins to trim in mm, inches, or points, or click Auto-crop to remove white margins automatically. The dimmed area shows what will be cut.
- 3
Pick the pages
Apply the crop to all pages, just the current page, or a page range like 2–5, 8. Thumbnails show which pages will be affected.
- 4
Crop & download
Click "Crop & Download PDF". A new cropped file is built on your device — the original stays untouched, and the trimmed content remains recoverable inside the file.
What You Can Use This For
A handful of situations cover almost every reason people crop a PDF:
Remove white margins from scans
Scanned pages often have thick borders with the content floating inside. Auto-crop trims the white space so the document reads and prints tight.
Crop a shipping label or receipt
Pull a single label, ticket, or receipt out of a full page so it prints at the right size without a sheet of empty space around it.
Strip headers, footers, or watermarks
Trim a running header, footer, or margin watermark off every page with one crop applied to the whole document.
Tidy slide or screenshot exports
Slides and screenshots exported to PDF often carry extra chrome. Crop to the content area for clean handouts.
Make a PDF easier to read on a phone
Crop wide margins so the text column fills a phone screen — no pinch-zooming every paragraph.
Unify the visible area across pages
Apply the same crop box to every page so a mixed document presents a consistent, margin-free frame.
Crop, Resize, or Compress — Which Do You Need?
These three jobs are easy to confuse because they all "change" the PDF. They do completely different things:
Change the visible area
Trims the page down to a chosen region by setting a new crop box. Use it to cut margins, borders, headers, or white space. The page's format and file size barely change.
Change the page format
Scales pages to a new paper size like A4, Letter, or custom dimensions. Use it when the format is wrong, not when there's extra margin to trim.
Resize PDF →Reduce the file size in MB
Shrinks the megabytes for email or upload limits by re-encoding images and fonts. Cropping does not meaningfully reduce file size — compression does.
Compress PDF →Browser-Based vs Upload-Based PDF Croppers
Every tool that can crop a PDF works either on a company's server or on your own device:
| Aspect | This tool (in your browser) | Typical online croppers (upload) |
|---|---|---|
| Where your file goes | Never leaves your device | Uploaded to a server |
| Account required | No account, ever | Some require sign-in (e.g. Adobe) |
| Auto-crop white margins | Yes, built in | Rare on free browser tools |
| Crop methods | Drag, exact margins, auto | Usually drag only |
| Page scope | All, a range, or one page | Often whole file only |
| Limits | No size, page, or task limits | Hourly quotas and size caps on free tiers |
One scope note: cropping hides the trimmed area but keeps it inside the file, and it won't make the PDF much smaller in megabytes. If you need a smaller file, compress it; if you need a different paper size, resize it — both also run entirely in your browser.

Frequently Asked Questions
Everything people ask about cropping a PDF
How do I crop a PDF for free?
Open the PDF above, select the area to keep, and download. Drag a box on the page, enter exact margins, or click Auto-crop, choose which pages to apply it to, and click crop. The whole process runs in your browser and is free with no limits.
Can I crop a PDF without Adobe Acrobat?
Yes — and you don't need an account at all. Adobe's online crop tool makes you sign in, and Acrobat hides cropping behind a subscription. This tool crops in one screen, free, with no installation and no login.
Is cropping a PDF permanent? Does it delete the content?
No — cropping hides the margins, it does not delete them. Cropping sets a new crop box, so the trimmed area is moved outside the visible region but stays inside the file and can be restored by widening the crop again. It's the same lossless, reversible approach Adobe and Sejda use.
Will cropping reduce my PDF's file size?
Not noticeably — the megabytes stay roughly the same. Because the trimmed content is hidden rather than removed, the file size barely changes. If a smaller download is what you need, compress the PDF instead.
How do I remove white margins from a scanned PDF?
Click Auto-crop to detect the content and trim the white space. Auto-crop finds the content boundary on the page and crops to it automatically. For a multi-page scan, apply it to all pages so each one is trimmed to its own content.
Can I crop all pages at once, or just some?
Both — apply to all pages, the current page, or a range. Choose the scope before downloading: every page, just the page you're viewing, or a range like 2–5, 8. The same crop box is applied to each selected page.
Will cropping lower the quality?
No — cropping is lossless. It only changes the visible area by adjusting the crop box. Text and vector graphics are never re-encoded, so the cropped pages stay perfectly sharp at any zoom.
Are my files uploaded to a server?
No — everything happens in your browser. Your PDF is opened and cropped locally on your device and never uploaded, so no copy is left on any server. You can even crop with your internet disconnected once the page has loaded.
