Image Resize
Resize PNG, JPG or WebP images by width, height or percentage. Preserves aspect ratio. Runs entirely in your browser.
Built for fast, private, no-nonsense work.
Image Resize is part of PixHaul — a small set of browser-based tools we built because most of the “free online” alternatives are slow, ad-laden, and upload your files before they’ll process them. PixHaul does none of that.
Image Resize in four steps.
- 1
Drop the image
Drag a PNG, JPG or WebP onto the drop area. We read its dimensions immediately.
- 2
Set new dimensions
Type a new width or height in pixels, or use the percentage chips (25 %, 50 %, 200 % …). With the aspect-ratio lock on, the other dimension updates to match.
- 3
Pick the output format
Keep the original format, or switch to JPG for smaller files or WebP for the best size-vs-quality balance.
- 4
Resize and save
Click Resize to render the new image, then Save to download it. The filename includes the new dimensions for easy identification.
Questions, asked & answered.
Will resizing lose quality?
Downscaling preserves quality well — we use the browser’s high-quality bicubic resampling. Upscaling beyond the original dimensions will always look softer because no resizer can invent detail that wasn’t in the source pixels.
Can I resize multiple images at once?
Right now we resize one at a time to keep the UI focused. Multi-image batch resize is on the roadmap.
What’s the maximum image size you can handle?
Up to roughly 30–50 megapixels in most modern browsers. The actual limit depends on your device’s available memory.
Are the resized images uploaded anywhere?
No. The resize happens entirely in your browser using the Canvas API. The image, the result, and the metadata never leave your device.
How do I keep the aspect ratio?
Leave the “Lock aspect ratio” checkbox on (it’s on by default). When you change one dimension, the other updates automatically.
Can I convert format and resize in one step?
Yes — pick a different format in the Output panel and the resized image will be saved in that format with no extra steps.
How is this different from other online image resizers?
Most other tool sites upload your image to a server and rate-limit free users. PixHaul resizes in your browser with no quotas and no watermark.
