TinyPNG is great, but it limits free files to 5 MB and uploads every image to its servers. These alternatives compress images with more control, bigger files or full privacy.
Compress in your browser with side-by-side preview and modern formats.
Squoosh is an open-source image compressor built by Google Chrome Labs. You drop in a photo, pick an output format such as WebP, AVIF, MozJPEG or OxiPNG, and drag a slider to compare the original and the compressed version side by side before you save it.
Batch compress, resize and convert images.
iLoveIMG is a collection of simple image tools from the team behind iLovePDF. Compress, resize, crop, convert, rotate, watermark and upscale images, or turn a photo into a meme, all from a clean interface.
Resize hundreds of photos locally.
Bulk Resize Photos does one job: resize lots of images at once. Pick or drag in your photos, choose a scale, a longest side, an exact width or height, or a target file size, and it processes them all together.
Convert images to WebP, AVIF and more on your device.
VERT is an open-source file converter with a clean, modern interface. Drop in images, audio files or documents and pick a target format; it converts them with WebAssembly right on your device, so those files are never uploaded.
Shrink SVG files with live preview.
SVGOMG is a web interface for SVGO, the popular SVG optimizer, made by Jake Archibald. Paste SVG markup or open a file, and it strips editor metadata, comments, hidden elements and unneeded precision to make the file much smaller.
Optimize and compress animated GIFs.
ezgif is a no-nonsense toolbox for animated GIFs. It can turn a video clip or a set of images into a GIF, then resize, crop, rotate, speed up, reverse, add text or optimize it so the file gets smaller.
Squoosh is our top pick. Compress in your browser with side-by-side preview and modern formats.
