Image Resizer — Exact Pixel Dimensions
Resize any image to a specific width and height — or a percentage of the original. Lock aspect ratio, pick output format, choose quality. Runs in your browser; nothing is uploaded.
Drop an image, or click to select
PNG, JPG, WebP — anything browsers display
Resizing happens in your browser via the Canvas API. Your image is never uploaded — verifiable in DevTools → Network during use.
FAQ
Is my image uploaded?▼
No. Resizing happens entirely in your browser using the Canvas API. The image never leaves your device — verifiable in DevTools → Network: zero requests during the resize.
What's the difference between this and an image compressor?▼
A compressor reduces file size while keeping pixel dimensions roughly the same (or doing minor downsizing). A resizer changes the actual pixel dimensions — going from 4000×3000 to 800×600 for a website thumbnail, for example. The two are often used together.
Can I resize by percentage instead of pixels?▼
Yes — switch the unit toggle to %. Entering 50% on a 4000×3000 image gives you 2000×1500.
Will it preserve aspect ratio?▼
By default, yes — the lock icon next to the dimensions ties width and height together. Click the lock to free them and resize to any non-proportional shape.
What output formats are supported?▼
Keep original (PNG/JPG/WebP), or convert to PNG, JPG, or WebP. JPG and WebP have a quality slider (60–100%); PNG is always lossless.
What's the maximum image size?▼
Browser memory permitting, single images up to ~50 megapixels resize comfortably. Above 100 MP, expect slowdowns on phones; desktops handle bigger.
