Resize Photos: Change Width and Height
ReadyChange an image’s pixel dimensions. Enter photo width and height to create a resized output; pixel resizing does not set a target file size in KB.
All tools are free to use. File size and processing limits may vary by tool.
Processing stays on your device. Up to 20 images, 50 MB total; 20 MB and 16 megapixels per file. Output up to 16 megapixels and 8000 px per edge. JPG flattens transparency onto the selected background.

How to resize?
Upload the image and type the exact width and height; the tool produces a file in precisely that size. No cropping, so work out the ratio yourself.
Browser tools keep files on your device. Advanced document tools upload files for temporary server processing; the tool shows this before upload. Web lookups send queries to the server and public lookup services.
Resize an image without distorting its proportions
Resizing changes pixel width and height. Cropping removes part of the picture. A smaller card may only need resizing; fitting a subject into a square may require cropping first. Mixing up these operations can make objects look stretched or flattened.

Image Compressor
Reduce JPG, PNG and WebP file sizes. Choose image quality or a target KB size and compress individual photos or batches in your browser.
Crop Image
Crop images in the browser. Drag the edge guides on the preview to mark the area, then download as PNG or JPG. Up to 20 MB and 40 megapixels, and files are never uploaded.
JPG to PNG
Select a JPG and run it; the lossless PNG version downloads. If the photo has no transparency, only the format changes. Files are processed in this browser and never uploaded.
PNG to JPG
Upload a PNG and run it; transparent areas fill white and a JPG downloads. Ideal for shares that need small files. Files are processed in this browser and never uploaded.
WebP to JPG
Upload a WebP file and run it; the classic JPG version that opens everywhere downloads. Transparent areas fill white. Files are processed in this browser and never uploaded.
Background Remover
Remove the background from a JPG, PNG or WebP photo and download a transparent PNG. Check hair, glass and fine edges in product or profile images.
Continue with this image
Next-tool options appear beside the output image. Choose individual images in batch results. The image arrives selected; processing does not start automatically. Later operations may change size, dimensions or transparency; check the result.
Transfer happens between open tabs; we do not save the file in browser storage for this. This step does not start a new upload. Choosing server processing in the destination uploads the file again; its size limit applies.
Where can you use this on social media?
YouTube
Prepare a 16:9 frame for a YouTube video thumbnail, then check text readability and file size. Compressing an image does not compress a video.
Instagram
Prepare square or 4:5 artwork for an Instagram post, or 9:16 for a story. These are working options. Check cropping in the profile grid and app before posting.
TikTok
Prepare a 9:16 photo or vertical cover for TikTok. Keep titles away from edges where app controls may overlap. Image tools do not produce videos.
Facebook
Use images in Facebook posts, product pictures or link sharing. A 1200 × 630 working canvas is an option for link images; check the final view on phone and desktop.
