About this tool
This free online image tool resizes, crops, rotates, compresses, and converts images — all in one place and entirely in your browser. Load an image once and apply any combination at the same time: the operations stack (crop → rotate/flip → resize) and feed a single live preview, so you never have to re-upload between steps. Pick the output format (PNG, JPEG, or WebP) with a quality slider to shrink the file. Nothing is uploaded, so it's fast and private.
How to use
- Choose an image from your device.
- Rotate/flip, crop, and resize as needed — they all apply together.
- Set the output format and quality to compress or convert.
- Download the finished image.
Tips for the best result
- Keep the aspect ratio locked(the default) so the image doesn't stretch — turn it off only when you deliberately want a different shape, and crop instead of stretching where you can.
- Don't upscale. Enlarging a small image just adds blur; it can't invent detail.
- Size to the space it will fill — serving an image far larger than it's displayed wastes bandwidth for no visible gain.
Why browser-based
Editing images on-device means no upload wait, no server storing your photos, and no privacy worries — ideal for screenshots, ID photos, product images, and anything sensitive. If your goal is purely a smaller file, the image compressor is a one-step tool for that, and our guide to resizing and cropping images for the web covers the approach in depth.
Frequently asked questions
What can this image tool do?
It's an all-in-one image editor: crop, rotate and flip, resize to exact dimensions, and export as PNG, JPEG, or WebP with adjustable quality to compress or convert. All of these stack on a single uploaded image — no re-uploading between steps.
Are my images uploaded to a server?
No. Everything happens in your browser using the HTML canvas — your image never leaves your device, which is faster and fully private.
How do I compress an image?
Choose JPEG or WebP in the Output section and lower the Quality slider. The result's file size updates so you can balance size and quality, then download.
How do I convert between PNG, JPEG, and WebP?
Pick the target format in the Output section and download — the image is re-encoded in that format. WebP usually gives the smallest files.
Does resizing keep the aspect ratio?
Yes by default — change width or height and the other follows. Toggle to 'Aspect free' to set both independently and stretch the image.
Is it free and is there a size limit?
It's completely free with no sign-up. Because processing is local, very large images depend on your device's memory, but typical photos work fine.
