Resize image

Change image dimensions in pixels

Phone photos are often 4000+ pixels wide, far more than a website, profile picture, marketplace listing or email needs. pdfty's image resizer scales images to the exact pixel dimensions you choose, which also makes files much smaller and faster to load. Typical uses: avatars, marketplace photos, newsletter images and blog illustrations.

Enter a width and height in pixels. With “keep aspect ratio” on (the default), the image is scaled to fit inside that box without distortion — so 1200×1200 turns a landscape photo into 1200 px wide and proportionally shorter. Turn it off to stretch the image to exactly the size you typed, which is useful for fixed slots but can distort faces and logos. Resizing runs on our server with Pillow, and EXIF rotation is applied.

Upload several images at once and get a ZIP. Free: no daily limit, up to 20 MB per file, no watermark, no sign-up. Files are deleted within 1 hour. Every image in a batch uses the same width, height and aspect-ratio setting. Run Compress Image afterwards if you need the files even smaller.
