How to resize an image online
Add your images
Drag and drop or pick JPG, PNG, WebP, GIF or SVG files. They are processed on your device and never uploaded.
Choose a size
Enter exact width and height, pick a percentage, or select a ready-made preset for YouTube, Google Play, app icons, Instagram and more.
Download
Resizing happens instantly in your browser. Download one image, or grab them all as a ZIP — with no watermark.
Pixels, percentage, or ready-made presets
Set the exact width and height in pixels with the aspect ratio locked, scale by a percentage like 25%, 50% or 75%, or jump straight to a platform preset. The preset library covers YouTube, Google Play, App Store and Android, Instagram, Facebook, X, LinkedIn and website sizes — so you never have to look the numbers up.
When a target has fixed dimensions, choose how the image fills it: Crop to fit centers and trims the overflow (great for icons and thumbnails), Fit inside scales the whole image in and pads the rest with a background color of your choice, and Stretch forces the exact size. Turn on Do not enlarge if smaller to avoid upscaling.
Private, free, and right in your browser
Every resize runs locally using the Canvas API and Web Workers, so even a folder of large photos stays on your device: nothing is uploaded, and there is no sign-up or watermark. A batch holds up to 60 images of up to 60 MB each. Need smaller files too? Send the resized images through the Image Compressor, or build a PDF with the PDF & image tools.
Frequently asked questions
How do I resize an image online?
Add your image, choose a size by exact pixels, a percentage, or a preset, and download the result. With this tool everything happens in your browser, so the resize is instant and your file is never uploaded.
Can I resize an image to 1280x720 for YouTube?
Yes. Open the Presets tab and pick YouTube Thumbnail (1280×720). Crop to fit keeps a clean 16:9 frame with no stretching.
Can I resize an image to 512x512 for Google Play?
Yes. Choose the Google Play App Icon preset (512×512) or use the Google Play icon resizer, which opens with it selected. Either way the output switches to PNG, the format Play requires for the icon.
Are my images uploaded to a server?
No. All resizing is done locally in your browser with the Canvas API. Your images never leave your device — nothing is uploaded, stored, or sent anywhere.
Can I resize multiple images at once?
Yes. Drop or select many images and they all resize in batch to the same size, then download them individually or together as a single ZIP file.
What is the best image size for Instagram?
Square posts are 1080×1080, portrait posts 1080×1350, and Stories or Reels 1080×1920. All three are in the Instagram tab of the Presets panel.
Can I resize without losing quality?
Resizing down preserves quality well; export as PNG for lossless output, or WebP/JPG with the quality slider for smaller files. Avoid enlarging small images — turn on “Do not enlarge if smaller” to prevent upscaling.
Can I crop instead of stretching?
Yes. Choose Crop to fit to fill the target size without distortion (the overflow is trimmed), Fit inside to letterbox the whole image with a background color, or Stretch only when you intentionally want to force the exact dimensions.
How do I resize an image to a favicon?
Open Presets, choose Website / SEO, then Favicon (32×32). Use Crop to fit for a square logo or Fit inside for a wide one, and keep the PNG output. For another size such as 16×16 or 48×48, switch to Dimensions, turn off Maintain aspect ratio and type both numbers. This tool writes PNG files, not the .ico format.
What size should a Facebook cover photo be?
The Facebook Cover preset exports 1640×924 px, a 16:9 image. Facebook shows a Page cover in full on phones and crops the top and bottom of it on a computer, so keep text, logos and faces in the middle band of the image. The reasoning is in the guide to Facebook cover photo size.
