Dynamic Conversion Insights
Upload an image to choose an output format and preview the result.
WebP often reduces file size while preserving good visual quality.
Metadata such as EXIF camera details is not copied into the converted file.
Preview the converted image before replacing your original file.
Resize is off, so the original dimensions are kept, up to 4096px on the longest side.
How Image Conversion Works
Image conversion changes the file format used to store the image.
Your browser decodes the image, draws it onto a canvas, and exports the canvas in the format you choose.
JPG and WebP are lossy here: the quality setting trades detail for file size.
PNG is lossless, so it keeps every pixel but is often larger for photos.
Transparency and animation support depends on the format.
Canvas export does not copy metadata such as EXIF camera details or GPS location.
JPG, PNG, WebP, GIF, SVG, and Format Differences Explained
JPG is efficient for photos but does not support transparency. This tool always fills transparent areas with the background color (white by default).
PNG supports transparency and works well for screenshots or logos. Transparency is kept when Preserve transparency is on.
WebP often gives smaller files with good quality and supports transparency, which is kept when Preserve transparency is on.
GIF can be animated, but canvas conversion may only handle one frame.
SVG is vector-based and should be handled carefully.
Format choice affects file size, quality, transparency, and compatibility.
Transparency, Quality, File Size, and Browser Support Notes
Converting transparent images to JPG flattens transparency.
The quality slider applies to JPG and WebP. It is disabled for PNG.
PNG export may not shrink photos much.
If your browser cannot export WebP, the tool shows an error instead of saving a different format under a .webp name.
Output is limited to 4096px on the longest side. Larger images are scaled down and a warning is shown.
Metadata such as EXIF is not copied into the converted file.
Animated images may lose animation if converted through a simple canvas workflow.

Image Converter vs Image Compressor vs Image Resizer
Image Converter changes the file format, for example PNG to JPG or JPG to WebP. Quality and resizing are optional extras.
Image Compressor is mainly for making a file smaller while keeping a format you can use.
Image Resizer is mainly for changing pixel dimensions, such as fitting an image to a set width or percentage.
Converting can change file size as a side effect, and it can grow as well as shrink. If a smaller file is the goal, a compressor is the better fit.
