Crop images
Crop a whole batch to the same shape. Pick a ratio for the platform you are posting to, or exact pixels, and choose which part of the frame survives.
How to crop images
- Add your images — mixed sizes and orientations are fine.
- Pick an aspect ratio: 1:1 for a square post, 4:5 for an Instagram portrait, 9:16 for a story or Reel, 16:9 for a thumbnail or slide.
- Choose which part to keep. Centre works for most photos, but Top is usually right for portraits, where centring cuts off foreheads.
- Press Crop. The largest possible crop of that shape is taken from each image, so nothing is scaled or stretched.
Why this one is different
Almost every free file tool works the same way: you upload your file to a company's server, their machine does the work, and you download the result. That means a copy of your document sat on someone else's hard drive, governed by a privacy policy you did not read.
Filebench does the work in the browser tab you are already looking at. There is no upload step because there is no server to upload to. The practical consequences: no file size limit, no queue, no account, no watermark, and it keeps working if your connection drops after the page loads.
| Filebench | Typical online converter | |
|---|---|---|
| Your file leaves your device | Never | Every time |
| File size limit | None | Often 10–100 MB free |
| Sign-up required | No | Usually, past a few files |
| Watermark on output | No | Sometimes |
| Works offline after loading | Yes | No |
Questions
Does cropping reduce quality?
No pixels are resampled — the crop takes a rectangle out of the original at full resolution. The only quality change comes from re-encoding, so use PNG output, or a high JPG quality, if you want to be strict about it.
What ratio should I use for Instagram?
1:1 for a classic square post, 4:5 for a portrait feed post (which takes up the most vertical space in the feed), and 9:16 for stories and Reels. All three are in the ratio list.
Why is Top usually better than Centre for portraits?
Because faces sit in the upper third of most portrait photos. A centre crop to 1:1 from a tall photo removes equal amounts from top and bottom, which frequently takes the top of the head with it.
Can I crop to a specific position rather than an edge?
Not yet — the current version anchors to the centre or one edge. A drag-to-position crop box is the most requested addition and is next on the list.
What happens if my image is smaller than the pixel size I asked for?
The crop is clamped to the image, so you get the largest rectangle that actually exists rather than a padded or upscaled result.
