Choose the right balance of size and clarity
Choose an image, select an output format and a quality preset, then convert to inspect the result before downloading. You can also optimize an image without changing its format. All image processing happens locally in your browser; image files are not uploaded by this tool.
Smaller files
Try WebP or JPG with the Smaller file preset. Set a maximum file size to let the converter search for a suitable quality level. Allow smaller dimensions if meeting the size target matters more than retaining the original resolution. Results depend on the image; the tool reports when it cannot reach your target.
Clearer images
Use Higher clarity and retain the original dimensions. PNG preserves rendered pixels without lossy encoding and works well for text, screenshots and transparent graphics. Light sharpening can emphasize edges, but cannot restore detail missing from the original. Enlarging an image does not create true additional detail.
Remove image metadata
The default mode creates a new image from rendered pixels, discarding source EXIF, GPS coordinates, camera information, XMP and comments. Standard output format headers may remain. Visible text, watermarks and identifying content within the image are not removed. Choose Keep original file unchanged to preserve the original bytes and metadata; this mode skips all edits and compression.
Formats and transparency
JPG is useful for photographs and uses a solid background. WebP offers compression and transparency. PNG uses lossless pixel encoding with transparency. BMP exports a genuine uncompressed 24-bit bitmap and is usually large. AVIF encoding uses a WebAssembly version of libavif in a background worker, even when the browser cannot natively export AVIF. AVIF support loads on demand from this website and can be cached by your browser. Image pixels stay on your device. Reading an AVIF file also requires browser decoding support. Unsupported formats are never silently saved under an incorrect extension.
Before you download
Compare the original and result, inspect at actual pixel size, and check the byte count and dimensions. Animated input becomes a still image. Canvas processing may change HDR or wide-gamut colors. Source image orientation follows the browser decoder. PNG is lossless relative to the rendered output, not necessarily identical to the source file after resizing, rotation or color conversion.
