Is it private and safe to use?

Yes. Compress an image to a target file size runs entirely in your browser — your files are processed on your device and are never uploaded to a server, so no one else can see them. It is free, needs no sign-up, and works offline.

Can I enter a size other than 20, 50, 100, or 200 KB?

Yes. The buttons are shortcuts, but you can enter any whole-number target from 10 KB to 5,000 KB.

Will Pixo always hit the exact target?

Pixo aims to stay under the selected limit while preserving as much quality as possible. Some images and formats cannot reach an extremely small target without resizing; when that happens, Pixo shows the closest result instead of silently changing the format.

Which input formats are supported?

The target-size tool accepts JPG, PNG, WebP, and GIF. AVIF is available as an output format elsewhere in Pixo but is not accepted as an input here.

Compress an image to a target file size

Set the file-size limit your form, email, profile, or portal requires. Choose a preset such as 20, 50, 100, or 200 KB—or enter your own target—and Pixo searches for the best result it can make without uploading the image or changing its format.

Quick answer

Compress an image to a target file size is a free browser tool that reduces image file size while letting you control quality or dimensions. It accepts JPG, PNG, WebP, or GIF images, produces optimized image files, and handles one source at a time. Processing happens locally in this browser; source files are not uploaded to Pixo. No account or software installation is required.

How it works

01
Set the limit
Choose a common preset or enter any whole-number target from 10 KB to 5,000 KB.
02
Drop a supported image
Select a JPG, PNG, WebP, or GIF. The file is read directly from your device and never uploaded to Pixo.
03
Pixo searches for the best fit
JPG and WebP use quality search; PNG and GIF use palette reduction. You see the exact result size before downloading.

Tips for better results

Targets around 20–50 KB suit strict forms and small avatars; 100–200 KB usually preserves more detail for profiles, email, and documents.
If a large photo cannot reach a very small target, reduce its pixel dimensions first and then run the target-size compressor again.
Pixo keeps the source format: JPG stays JPG, PNG stays PNG, WebP stays WebP, and GIF stays GIF.

When to use this tool

Use Compress an image to a target file size when you need smaller images for a website, form, message, or storage limit without blindly accepting an unreadable result. Check the result before saving or sharing it so the output matches the destination’s practical, technical, and privacy requirements.
