Free Image Compressor
Shrink file size and optionally resize — by percentage or exact pixel dimensions — right in your browser. Nothing is ever uploaded.

or click to browse — JPG, PNG, WebP, AVIF, HEIC, GIF, BMP
Lower quality = smaller file. Works best for JPG and WebP; PNG has no quality dial (it's lossless).

What's the difference between percentage and pixel resize?
Percentage scales every image proportionally by the same amount (e.g. 50% makes everything half size). Pixel mode fits each image within a maximum width/height box — useful when you need images to never exceed a specific size, regardless of their original dimensions.
Will resizing distort my image?
No — both modes preserve the original aspect ratio exactly. Pixel mode fits within your box without stretching; it also never enlarges an image beyond its original size, since upscaling doesn't recover detail that isn't there.
