Resize images
Make pictures the exact size you need, whether that is 1080 by 1080 for Instagram, 35 by 45 millimetres for a passport or simply half the size. Resize in bulk, keep the aspect ratio or crop to fill, and optionally aim for a target file size in KB.

Questions and answers
How do I resize an image to under 100 KB?
Set a target file size of 100 KB. The tool lowers the quality, and the dimensions if needed, until the result fits.
Will resizing stretch my photo?
Not unless you choose Stretch. Fit inside keeps the whole picture, and Fill and crop trims the edges.
Are my images uploaded?
No, resizing runs in your browser.
