Open toolOnline Image Editor
A quick, free photo editor for the edits people actually need: resize an image to exact dimensions, crop it to a square or a 16:9 banner, rotate or flip it, and fix the look with brightness, contrast and saturation sliders — plus one-click greyscale and sepia. This online image editor runs entirely in your browser, so the photo you open is never uploaded to a server; it is the safe choice for product photos, listing images and personal pictures. Edits are non-destructive while you work: every adjustment re-renders from your original file, so you can experiment freely and only download when it looks right, as PNG or JPG.
How to use this tool
- Open an image and see it on the canvas.
- Crop to square, 4:3, 3:2, 16:9 or 4:5 with one tap.
- Rotate, flip and move the adjustment sliders.
- Optionally set an exact output width, then download PNG or JPG.
Worked example
A tall phone photo becomes a 16:9 banner: crop, a small brightness lift, resize to 1200 px wide and download — ready for a blog header.
Frequently asked questions
Is the original photo changed or uploaded?
Neither. The editor loads your file into the browser and keeps it untouched in memory; every slider and button re-draws the preview from that original, so edits never stack up damage the way repeated saving in some apps does. Nothing is uploaded — close the tab and the image is gone. The only file created is the one you download.
Which crop shape should I use for social media?
Square (1:1) is the safe all-rounder for feeds and marketplace listings. Portrait 4:5 takes up the most vertical space in Instagram-style feeds. 16:9 suits YouTube thumbnails, banners and slides, while 3:2 matches many cameras and blog featured images, and 4:3 is common for older listings and some ad formats. This editor centre-crops, so keep the subject near the middle before cropping.
Why does my resized image still have a large file size?
Dimensions and file size are related but different: a 1200 px PNG photo can still be several megabytes because PNG is lossless. If file size is what matters — for a website or an upload limit — download as JPG, or run the PNG through the image converter and export WebP at around 80% quality. Resize first, then convert: the combination gets most photos under a few hundred kilobytes.
Can I undo a single adjustment?
Yes — every control is independent. Move a slider back to 100%, tap a toggle again to switch it off, choose "No crop", or press Reset all edits to start over from the original image. Because each render starts from the untouched original, experimenting costs nothing and the downloaded file is always a fresh render at full quality.
