Change image size in pixels and ready-made sizes
To change the size of an image, set the width and height in pixels in the boxes above and download the result. This pixel resize works on JPG, PNG and WebP, keeps the quality as high as possible, and never uploads your photo.
You can change the dimensions of an image in three ways: type exact numbers (for example 690 × 500 px), use a ready-made size from the list below, or keep the original shape by changing only one side and letting the other follow the aspect ratio.

Pick the size from where the picture will be used. For social media: 1080×1080 (Instagram square), 1080×1350 (portrait), 1080×1920 (Stories, Reels, TikTok), 1280×720 (YouTube thumbnails), 1200×630 (link previews). For shops: 2000×2000 (Amazon), 1600×1600 (eBay), 2048×2048 (Shopify). For forms and ID photos use the exact pixels the form states.
The three fit modes: Crop to fill keeps the shape and cuts the edges, Fit inside keeps the whole picture and adds white bars, and Stretch forces the exact size and changes the shape. Crop to fill is the best choice for most photos.
Pixels, inches and print: for screens only the pixel size matters. For printing multiply the print size in inches by 300, so a 4×6 inch print needs 1200×1800 pixels. Shrinking keeps pictures sharp; enlarging cannot add detail, so start from the largest original you have.
If the file is too big after resizing, use the compressor, or read how to resize an image without losing quality.
Questions
How do I resize an image to exact pixels?
Choose your picture, type the width and height you need and press the picture. Then download the resized file.
What does Crop to fill mean?
The picture is scaled until it covers the whole frame and the extra edges are cut off. It never leaves empty bars.
What is the difference between Crop to fill, Fit inside and Stretch?
Crop to fill keeps the shape and cuts the edges. Fit inside keeps the whole picture and adds white bars. Stretch changes the shape of the picture to fit exactly.
Is my image uploaded?
No. Resizing happens in your browser.
Is there a size limit?
You can set a width and height up to 8000 pixels.
Does resizing reduce the file size?
Usually yes, because fewer pixels mean a smaller file, but not always by a set amount. If you need an exact file size, resize first and then use the compressor.
What size should I use for Instagram or YouTube?
Use 1080 by 1080 for Instagram squares, 1080 by 1350 for portrait posts, 1080 by 1920 for Stories and Reels, and 1280 by 720 for YouTube thumbnails.
How do I resize without losing quality?
Start from the largest original, make the picture smaller rather than larger, keep the shape and save as a high-quality JPG or PNG. Our guide explains it step by step.
