The file is always too large for wherever it's going. Email providers cap attachments at 10 to 25 MB. Government portals want your photo under 100 KB. Product images load faster below 200 KB. Set a target file size and the image size reducer compresses to match while keeping the image sharp.
Need to reduce a JPG file size for an email attachment? Decrease an image below 100 KB for a government form? Type the number, and the resizer finds the right compression level to match it.

Photos and images with millions of colors. Smallest file size for photographs.
Supports transparency. Best for logos, icons, and graphics with sharp edges.
Modern format. 30% smaller than JPG at the same quality. Used by most browsers.
Upload a JPG, get a resized JPG. Upload a PNG with a transparent background, the transparency stays intact. WEBP files keep their size advantage after resizing. The format you put in is the format you get back.
In file size mode, PNG sources convert to JPG for compression since PNG is lossless and can't be quality-reduced. The tool tells you when this happens.
A US passport photo has to be 2x2 inches. Schengen visa forms ask for 35x45 millimeters. Instagram posts look sharpest at 1080x1080 pixels. Send a photo to print below 300 DPI and it comes out blurry.
Use pixels for anything that stays on screen. Switch to inches, centimeters, or millimeters when a form asks for physical measurements. The resizer converts between units and has presets for passport photos, social media, and standard print sizes.
