Image Resizer
Resize any image by exact pixels, percentage or max width/height, with aspect ratio lock — free, in your browser, no upload. Free to use right here — nothing to install, no account needed.
Resize any image to exact pixel dimensions, scale it by a percentage, or cap it to a maximum width or height — with the aspect ratio locked so nothing gets stretched. High-quality resampling keeps downsized photos crisp.
Like every Bloodweb tool, it runs locally in your browser: no upload, no watermark, no account. Combine it with the format and quality options to convert and compress in the same pass.
Frequently asked questions
How do I resize an image without stretching it?
Leave "Keep aspect ratio" ticked and enter just the width (or just the height) — the other dimension is calculated automatically.
Can I resize without losing quality?
Downsizing uses high-quality resampling and looks sharp. Enlarging beyond the original size can't invent detail, so upscaled images will soften — avoid enlarging if you can.
What's the best size for web images?
For full-width page images, 1600–2000px wide is plenty; for content images, 800–1200px. Export as WebP or JPG at 80–85% quality for the best size/quality balance.
