Image tools · Free to use
Make your image easier to share without guessing what you are giving up.
Choose an image to get started.
Choose a JPEG, PNG, or WebP image up to 15 MB and 40 megapixels.
Select JPEG or WebP, adjust quality, and optionally reduce the maximum width.
Generate a preview, compare the size with the original, and download the result.
Lower quality settings can reduce the file size but may create visible artifacts around fine details. Inspect faces, gradients, and small text in the output preview. The right setting depends on the image and where it will appear.
A large photo may contain more pixels than a particular placement needs. Reducing its width can save more space than changing quality alone. This tool preserves the aspect ratio and never enlarges the source.
Some images are already efficiently compressed and may become larger when re-encoded. The tool shows the actual before-and-after sizes. Keep the original when the export does not improve the result you need.
No. Compression happens locally in the browser.
No. Quality and dimensions affect size differently for each image. Adjust the settings and compare the generated file size.
No. Transparent areas are filled with the selected background. Use WebP when you need transparency.
Canvas exports do not preserve the original EXIF metadata. Keep the source file if you need its camera or location metadata.
