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.
