Resize images
Four modes covering every real resize case. Aspect ratio is preserved by default. Browser-only; files never leave your device.
Resize image
Drop a batch of JPGs or PNGs, pick a mode, hit Resize. The same spec applies to every file. Output keeps the source format.
Open the resizer →Four modes. Pick the one that matches your goal.
1. Limit the longest side
When you have a max dimension in mind (e.g. 2048 px) and want the source aspect ratio preserved. The most common ask.
2. Exact width × height
When the destination has a precise box (e.g. 1920×1080 for a thumbnail). Choose Fit to letterbox or Stretch to distort.
3. Percentage of source
When you want to halve a folder of photos without thinking about pixels. Scale 1–100% of the originals.
4. Keep the source size
A no-op pass-through. Useful when you want to apply Strip-EXIF or quality re-encode without changing dimensions.
About the resampling
Downscaling runs through the browser’s high-quality canvas resampler, the same one Chrome and Safari use for drawImage with imageSmoothingQuality: high. That’s a tuned bicubic-like filter, sharp enough that results are visually clean at every scale. We never upscale; asking for a larger output than the source is a no-op.
JPG output passes through a final canvas re-encode at quality 0.9 by default (adjustable in Advanced options). PNG output is lossless. EXIF is stripped by default; the orientation tag in any preserved EXIF is reset to 1 because pixels are decoded upright before resampling.
