Supported: JPG, PNG, WEBP

Maximum file size: 20MB

Compression mode

Quality: 80

Output format

JPG output fills transparent areas with white.

The preview shows your selected image before processing and the output after processing. Download the result to inspect it at full size.

Choose the output

Keep the original format or choose JPG, PNG or WebP. The quality control applies to JPG and WebP output; it is unavailable for PNG.

JPG output fills transparent areas with white. Changing a JPG to WebP does not remove a white background already in the picture.

Check the file size and format

Compare Original size and Result size before downloading. A format conversion can create a larger file.

When the format stays the same and there is no size saving, the tool keeps the original file. When you request another format, it keeps that output format and reports its actual size.

Open the downloaded image to check text, detail, and the background.

How to process an image

Choose a supported image.
Select an output format and, for JPG or WebP, adjust quality.
Select Process image, compare sizes, then download and inspect the result.

Changing quality or format clears the previous download. Process the image again before downloading the new settings.

Size, dimensions, and JPG files

Can I set 20KB, 50KB or 100KB?

Choose Target file size, select 20KB, 50KB, 100KB or another limit, then process the image. The tool adjusts JPG or WebP quality within a bounded range and reports whether the result meets the target. PNG has no quality adjustment. Dimensions stay unchanged; a target may not be achievable.

Can I change width and height?

Not in the current tool. Compression and format selection do not provide a resize control.

Do JPG and JPEG need separate conversion tools?

They are common extensions for the same format family. Renaming a different file does not turn it into a valid JPEG.
