PUT THE PIXELS ON TARGET.
Image Resizer brings the width and height of an image to the size you are aiming for. You write the target width between 16 and 10,000 pixels; the height is worked out by itself from the aspect ratio, so the framing is not distorted. The output format is WebP, PNG, JPG or AVIF; the quality has five levels, and because PNG is lossless the quality setting is not used there. EXIF information is deleted by default and kept if you want.
If you choose a size larger than the source, the image is not enlarged; enlarging adds no sharpness, it only inflates the file. For enlarging there is the “Image Upscaler” tool, which rebuilds detail with a neural network. One step is enough to bring a product photo to a store's size, a profile photo to a platform's limit or a blog image to the content width; shrinking also lowers the file size noticeably. You can upload up to 20 images at once; they are all processed with the same settings, and several files download as a single ZIP.
From start to finish
- Upload your image. Drag the file in or select it. The current dimensions are read.
- Write the target width. Enter the width in pixels; the height is worked out from the ratio. Choose the output format and the quality.
- Resize and download. The new dimensions and the file size appear. Download it; the copy on the server is deleted when you leave the tool.
Frequently asked questions
Can I set the height myself?
No; so that the framing is not distorted, the height is worked out from the ratio. To bring it to a particular aspect ratio (square, 4:5, 16:9), crop it first with “Image Crop” and then give the size here. For cover and post sizes, the “Thumbnail Resizer” offers ready platform sizes.
Does the quality drop when I shrink it?
The number of pixels goes down, but the image stays sharp at the size it is shown; the resampling is done with a high-quality filter. With JPG and WebP output the quality level comes into play as well; High or Balanced is enough.
Which size for a profile photo?
Most platforms want 400–800 pixels square and shrink anything larger themselves. 800 px wide, WebP or JPG, High quality is a safe choice; for square framing use “Image Crop” first.
Does my file stay on the server?
No. Your file reaches the server only to be processed and is deleted when the job is done; the output is deleted too once you download it and leave the tool. You don't need an account, a name or an email address, and your files are never sent to a third-party service. It is free to use: we set no hourly or daily quota on the number of jobs, we don't make you watch an ad before processing, and we add no watermark to the output.
