Re-encode PNG, JPEG, or static WebP with format and quality controls. Compare actual input and output sizes.
Crop PNG, JPEG, or WebP visually with draggable handles, aspect ratios, and precise pixel controls.
Mirror PNG, JPEG, or static WebP horizontally, vertically, or across both axes on your device.
Convert a JPEG image to PNG without another lossy encoding step. Apply its EXIF orientation automatically.
Convert a JPEG image to WebP with adjustable quality while retaining its oriented dimensions.
Convert a static PNG image to JPEG with adjustable quality and an explicit background for transparency.
Convert a static PNG image to WebP. Keep its dimensions and transparency with high-quality compression.
Re-encode PNG, JPEG, or static WebP to remove source EXIF, GPS, XMP, comments, and color profiles.
Resize PNG, JPEG, or static WebP to fit a box or use exact pixel dimensions, with optional enlargement.
Rotate PNG, JPEG, or static WebP by 90, 180, or 270 degrees with automatic EXIF orientation.
Convert a static WebP image to JPEG with adjustable quality and a background color for transparent areas.
Convert a static WebP image to PNG. Keep the original dimensions and transparent background.
Convert between JPG, PNG, and WebP, resize, crop, rotate, flip, compress, and strip metadata. Presets are avoided on purpose: you choose the quality and dimensions.
Images are decoded and re-encoded in the browser, which is why the tools state exactly which formats, color profiles, and animations they support.
Use JPEG or WebP for photographs, where lossy compression saves a lot of space with little visible difference. Use PNG for screenshots, logos, diagrams, and anything with text or transparency, where lossless compression keeps edges sharp. WebP covers both cases in modern browsers and is typically 25–35% smaller than JPEG, but some email clients, print services, and older applications still expect JPEG or PNG.
The converters move between these formats with explicit choices for quality and for the background colour that replaces transparency in JPEG. The compressor re-encodes an image at a chosen quality and shows the real size difference.
Photos from modern phones are 12 megapixels or more, far larger than any web page or email needs. Resizing to 1600–2000 pixels on the long side and compressing at quality 75–85 usually cuts the file size by more than 90% without visible loss. Crop to the aspect ratio your destination expects, and rotate images whose EXIF orientation is ignored by the site you upload to.
Before posting photos publicly, consider removing metadata. Original photos can carry the exact GPS location where they were taken, along with the date, time, and device details. All image processing happens in your browser, so private photos never leave your device.
