How to use this tool

Choose a JPEG, PNG or WebP file, or drag it onto the drop area.
Check the target size (currently 50 KB). It is editable, so change the number or the KB/MB unit if your limit differs.
Press the button. The tool scales the dimensions down first and lowers quality only if scaling alone is not enough.
Compare the preview and the measured output size with the original, and read any notes or warnings.
Download the new file. If it missed the target, adjust the target slightly or crop the original, and try again.

What to know before you resize Image to 50 KB

Resizing and compressing are related but different. Compressing changes how the image data is encoded, trading detail for a smaller file at the same pixel dimensions. Resizing changes the number of pixels, for instance from 4000 by 3000 down to 800 by 600. Fewer pixels means less data, so the file shrinks without losing sharpness per pixel. This page uses a resize-first strategy: it scales dimensions down, keeps quality high, and reduces quality only if scaling alone cannot reach 50 KB. That is ideal for oversized phone photos and camera originals, where the picture will be displayed small anyway. It is less suitable if you need to keep the original dimensions; in that case, the compress version of this target is the better choice.

Resize-first keeps the compression quality high and reduces pixel dimensions instead. It suits images that are far larger than they need to be, such as raw phone photos. The size you enter is a goal, not a promise: the result depends on the original image, its dimensions, its complexity, its format and your browser's encoder, and the tool reports the real size instead of assuming it.

Recommended settings and supported formats

Use this page when the pixel dimensions can change. Keep the original format for JPEG, or switch the output to JPEG or WebP for PNG photographs. If a form also demands a particular width and height, resize to those dimensions in an editor first.

Accepted input: JPEG, PNG and WebP (WebP depends on your browser). HEIC and AVIF are not supported. PNG is lossless, so it can only get smaller with fewer pixels unless you choose JPEG or WebP output.

Practical uses

Shrinking raw phone and camera photos for online forms
Preparing images for pages where only a small display size is needed
Reducing scans without heavy compression artefacts

Tips for a smaller file

Use resize-first when the image is much larger than the display size.
Do not upscale the result afterward; it will look soft.
Pick JPEG output for photographs.
If dimensions must stay fixed, use the compress page instead.

Frequently asked questions

What is the difference between resizing and compressing an image?

Resizing changes the pixel dimensions, such as making a photo 800 pixels wide instead of 4000. Compressing re-encodes the data at lower quality. This page resizes first and compresses only if needed.

Will resizing to 50 KB change my image's dimensions?

Yes, usually. To reach a small file size the tool reduces the width and height, and the new dimensions are shown with the result.

When should I use compress instead of resize?

Use the compress page when you want to keep the original dimensions as far as possible and accept lower quality instead.
