With fixed dimensions, the image is fitted inside the frame without stretching. Empty space is padded.

The image tool has not started. Check that the updated script.js is in the main project folder and open the site with Live Server.

A LITTLE HELP ALONG THE WAY

A better fit, in three steps.

For job applications, school forms, and everyday uploads.

01

Choose an image

Select a JPG, PNG, or WebP image from your device. Your original file remains unchanged.

02

Choose your settings

For conversion, choose a format. For compression, set the size limits and optional dimensions.

03

Review and download

Check the final size and image quality. Only your application portal can confirm acceptance.

What compression does

The diagram represents a smaller file, not a specific result.

Your actual file size and visual quality depend on the image and settings. Output can remain above the limit; check the result before downloading.

Good to know

Will the output be exactly the size I enter?

Not necessarily. The tool aims to produce a file at or below your maximum. If you set a minimum, it also checks that limit. Some combinations cannot be achieved, and the result will say so.

What happens if my image cannot fit?

You can still preview the closest result, but it may be outside your limits. Try a larger maximum, a different format, or smaller dimensions if your application permits them. Fixed dimensions are never silently changed.

What does convert-only mode do?

It re-encodes the image to JPG, PNG, or WebP without changing its displayed pixel dimensions or requiring a size target. JPEG replaces transparent areas with white. Re-encoding may remove metadata and affect quality. File size may increase.

Which format should I choose?

Use the format required by your application. JPG usually works well for photographs; PNG can preserve transparency but may be harder to fit into a small size. Browser support for WebP output varies.

Does my image leave my device?

This tool reads and processes the file in your browser and does not upload it. If this site later adds analytics, ads, or other services, their data practices must be disclosed separately.
