Image Tools
Image tasks need different controls depending on the goal. Change dimensions with the resizer, compare bytes and quality with the compressor, or switch between PNG, JPEG, and WebP with the converter. All three run in your browser without uploading files.
Choose the right tool
Image Resizer
Choose this when a CMS, documentation page, or thumbnail requires exact pixel dimensions.
Image Compressor
Choose this when the main goal is a smaller JPEG or WebP file and visual quality still matters.
Image Converter
Choose this when another application expects PNG, JPEG, or WebP instead of the current format.
All tools
Example workflow: prepare a large image for a web page
- Check the image's current dimensions and decide how wide it will actually appear on the page.
- Resize it to an appropriate width while keeping the aspect ratio, then download the result.
- Compare JPEG and WebP output at a few quality settings, checking text, edges, transparency, and the actual byte count.
Before you use the result
The output is newly encoded as a static image. Animation, embedded metadata, and color profiles are not preserved. JPEG fills transparency with white, and changing a file extension alone is not a real conversion.
Start from the visual requirement
Image file size is influenced by both pixel dimensions and encoding. If a 4000-pixel photo will only appear 800 pixels wide, reducing dimensions is usually the first useful step. The Image Resizer changes width and height and can preserve the original ratio. It does not crop; forcing a wide image into a square stretches it.
After sizing, use the Image Compressor to compare actual JPEG or WebP output sizes. A lower quality setting may save bytes but can blur small text or introduce artifacts around edges. The output panel shows the measured size change, including when an export grows larger. For a format requirement rather than a size target, use the Image Converter.
PNG is a useful choice for sharp interface graphics and transparency. JPEG works well for many photos, but transparent pixels become white. WebP can preserve transparency while offering a quality control for photographic content. A format conversion cannot restore image detail already lost in an earlier JPEG export.
These tools accept PNG, JPEG, and WebP files up to 20 MB and 40 megapixels. Output encoding depends on your browser. Always review the downloaded file in its final context, particularly when color accuracy, transparent backgrounds, or small text are important.
