Upload JPG photos or graphics, adjust dimensions in px, %, in, cm, or mm, and optimize compression quality.
To resize a JPEG image, upload your JPG or JPEG file (up to 50MB), select a measurement unit — pixels (px) for screen use, percent (%) for proportional scaling, inches (in) or centimeters (cm) for print, or millimeters (mm) for precise work — then enter the target width and height. Adjust the JPEG quality slider if needed (1–100%), or let the tool auto-optimize. Click Resize and download the compressed result instantly. Your image is processed entirely in your browser using WebAssembly — nothing is uploaded to any server. The tool preserves EXIF metadata by default and supports batch resizing of multiple JPEG files at once. Free, no account required, no watermarks.
Resize JPEGs to exact pixel dimensions for website headers, hero images, and thumbnails. Maintain fast page loads with optimized file sizes.
Resize photos to Instagram, Facebook, or Twitter image dimensions. Perfect square crops for posts and banner sizes for cover photos.
Resize JPEGs to physical dimensions in inches, centimeters, or millimeters at 300 DPI for print-ready output.
Compress large JPEG attachments to fit email size limits. Resize photos for embedding in documents and presentations.
Upload your JPEG image using the tool above, select your target dimensions and unit type (px, %, in, cm, or mm), adjust the quality slider if needed, then click Resize. Your image is processed entirely in your browser — no upload required.
Resizing to smaller dimensions generally preserves quality well. Enlarging a small image may introduce artifacts. Use the quality slider to balance file size and visual quality for your needs.
