Free Online Image Editor
This free image editor lets you edit a photo in the browser: crop, resize, rotate, flip, compress, and change the file format. There is no account, and the image is not uploaded to ToolGuru. Upload once, make the edits you need, then download.
Resize Images
Change width and height in pixels. Keep “Maintain aspect ratio” on if you want the photo to stay in proportion — changing width updates height, and the other way around. Use this when you need a specific size for a website, a form, or a smaller file to share.
Crop Images
Crop to keep the part of the picture that matters. Choose free crop or a ratio such as 1:1, 4:3, 3:2, or 16:9. Drag the box, resize it from the handles, or type X, Y, width, and height. Apply Crop to confirm, or Cancel to put the box back.
Rotate and Flip Images
Rotate left or right by 90°, rotate 180°, or flip horizontal and vertical. The preview updates straight away, and the downloaded file keeps that orientation — useful for phone photos that open on their side.
Compress Images
Reduce file size by choosing a lossy format such as JPG or WebP and lowering quality. Higher quality makes a larger file; lower quality makes a smaller one. Output size is calculated in your browser from the actual encoded file, not a guess. PNG stays lossless.
Change Image Format
Export to JPG, PNG, WebP, BMP, ICO, or AVIF when your browser can encode it. If you only need to convert many files without cropping or resizing, the Image Converter is built for batch format changes.
How to Edit an Image Online
Step 1
Choose an image
Drop a JPG, PNG, WebP, GIF, BMP, ICO, or AVIF file, or pick one from your device.
Step 2
Edit
Crop, resize, rotate, or flip. Apply crop and resize when you are happy with the preview.
Step 3
Optimize
Pick an output format and quality. JPG and BMP fill transparent areas with your background color.
Step 4
Download
Save the edited file to your device. Nothing is uploaded to ToolGuru.
Frequently Asked Questions
Is this image editor free?
Yes. You can crop, resize, rotate, flip, compress, and download images at no charge. No account is required.
Do I need to create an account?
No. You can edit and download without signing in.
Are my images uploaded to a server?
No. Editing runs in your browser. ToolGuru does not receive or store the image.
Can I crop and resize in the same session?
Yes. Upload once, then apply crop, resize, rotate, and flip in any order before you download. Reset restores the original image.
Does compressing reduce quality?
JPG, WebP, and AVIF are lossy, so you can set quality from 10% to 100% (default 80%). PNG, BMP, and ICO do not use a quality slider. Edits stay on a lossless working copy until you download.
Which formats can I open and save?
You can open JPG, PNG, WebP, GIF, BMP, ICO, and AVIF. You can save to JPG, PNG, WebP, BMP, ICO, and AVIF when your browser can encode that format. GIF output, TIFF, and SVG are not supported.
Can I edit several images at once?
This editor works on one image at a time. Use the Image Converter if you need to change the format of many files in one batch.
What happens to transparent PNG or WebP areas?
Transparency is kept for PNG, WebP, AVIF, and ICO. JPG and BMP cannot store transparency, so those pixels are filled with the background color you choose (white by default).
