- Open the file picker and choose the image you want to resize.
- Enter the width and height in pixels.
- Select a fit mode: Contain keeps the whole image visible inside your dimensions while preserving the aspect ratio, Cover fills the entire box and crops whatever overflows, and Stretch distorts the image to match your exact width and height.
- Download the resized image, which is produced instantly in your browser.
Every pixel is processed locally on your device — nothing is uploaded to a server. This makes it safe to resize personal photos and confidential work images alike.
Contain is ideal when you need the full image within a frame, even if that leaves a little empty space. Cover is best for thumbnails, banners and profile pictures where you want the frame fully filled. Stretch is useful when the exact dimensions matter more than the proportions, such as a social media header that must be a precise size.
Tips
Always use the highest-quality original you have, because resizing is a one-way operation that discards information. For cover mode, the edges that get cropped are chosen automatically, so it helps to know which part of the image matters most. When you need a same-size result with consistent dimensions across a set of images, cover mode keeps everything uniform.
If you are preparing images for the web, resizing to a sensible width first is usually smarter than relying on CSS alone — you save bandwidth without pulling down large files to every visitor. Because the tool is free and runs locally, there is no limit on how many images you adjust.
Why use it
Photo platforms, email campaigns and CMS systems often require specific image sizes. Resizing in the browser is faster than launching an editor, and it costs nothing. There are no size caps, no uploads, and no account needed — just pick a file, set your dimensions, and download.
Real-world use cases
- Blog and e-commerce: Shrink product photos from 4MB to ~200KB before upload. Your pages load faster and Google PageSpeed scores improve.
- Email and forms: Many inboxes reject >10MB attachments. Compress once and you reliably stay under limits.
- Portfolio and social: Keep visual quality high at 75-85% while cutting bandwidth for viewers on mobile data.
How it compares
| Tool | Upload required | Privacy | Batch | Cost |
|---|---|---|---|---|
| This tool | No | 100% local | 1-by-1 (high quality) | Free |
| TinyPNG/Squoosh | Yes / No | Server or local | Yes | Freemium |
| Photoshop | No | Local | Yes | Paid |
For sensitive images or quick one-offs, a local browser tool wins on privacy and speed. For massive bulk jobs, a desktop app may be faster.
Pro tips
- For photos, try quality 78-82% first. You usually save 60-70% size with no visible loss.
- Scale down dimensions before lowering quality. A 4000px photo at 2000px is 4x smaller even at high quality.
- Keep a backup of the original. You can always re-export at lower quality, but you cannot recover detail after saving over the original.
