Crop Image Online

FloxerFile lets you crop a JPG image directly in your browser. Whether you're removing an unwanted border, tightening the frame around a subject, or cutting out distracting edges, set the percentage to trim from each side and your image is cropped accordingly — no software, no sign-up.

How it works

1. 1

   Upload your JPG

   Drag and drop your JPG or JPEG image, or click to browse. Files up to 20 MB are supported.

2. 2

   Set your margins

   Enter the top, bottom, left, and right margins to remove, as a percentage of the image's width or height. Leave a field at 0 to keep that side unchanged.

3. 3

   Crop

   Click Crop Image. Your image is cropped to the new dimensions on our servers.

4. 4

   Download your cropped image

   Download the resulting JPG with the new margins applied.

Features

• Per-side margin control

  Set independent top, bottom, left, and right margins instead of a single uniform crop.

• Percentage-based

  Margins are set as a percentage of the image's dimensions, so they scale correctly for any image size.

• Content preserved

  Cropping only trims the visible frame — the remaining pixels are never altered.

• Privacy-first

  Files are processed in memory and deleted immediately after download.

• Free & no sign-up

  No account, no credit card. Crop as many images as you need.

• Works in the browser

  No software or plugins needed — upload, crop, and download entirely online.

Output format: .jpg

Frequently asked questions

What unit are the margins in?

Margins are entered as a percentage of the image's width or height, not absolute pixels. A 10% top margin trims 10% of the image's height from the top, regardless of the image's actual size.

What happens if I leave a margin empty?

Any margin left empty defaults to 0, meaning that side of the image is left untouched.

Can the margins be too large?

Yes. Each margin is capped at 49% individually, but if the combined margins on an axis leave nothing left to show, the tool rejects the request and asks you to use smaller values.

Will cropping change the quality of my image?

Cropping only trims the frame — the remaining pixels are not resized or re-processed beyond re-encoding to JPG.

Can I crop other image formats?

This tool only accepts JPG and JPEG files. Support for other source formats may be added in the future.

Are my files kept private?

Your files are processed on our servers solely to perform the crop. They are deleted automatically once the download is complete and are never shared or stored long-term.
