Type the width or height in pixels, or pick how much smaller in percent, and the picture resizes instantly. The preview is live while you adjust, and the moment you settle, the exact final pass runs: a true Lanczos resample, the same algorithm professional tools use, computed right in your browser. That is the difference you see at the edges: text stays crisp, lines stay clean, and photos shrink without turning mushy or jagged.
Pixel mode gives you width and height fields with an aspect ratio lock: type one side and the other follows automatically, or unlock to stretch freely. Percent mode shrinks by 25, 50 or 75 with one tap, or by any custom amount with the stepper, with the resulting dimensions always shown in the line above. Either way the numbers are exact: what the card says is precisely what downloads, and resizing to the original size simply hands back your original file untouched.
Quick resizers use the browser's default scaling, which blurs detail on big reductions and shimmers on fine patterns. Lanczos weighs every source pixel that should influence each output pixel, in both directions, with proper transparency handling. The result is the sharpest faithful version of your picture at the new size, downscaling or enlarging. Huge photos stay smooth to work with, since the computation runs in the background in small slices, never freezing the page.
Select or drop several pictures and they all resize together with the same settings, downloaded as one ZIP. Percent scales each image relative to its own size; a locked width gives every image that width with its height following its own proportions. Up to thirty images per batch, each resampled at the same Lanczos quality as a single resize.
The download starts in the format you uploaded, so a JPG comes back a smaller JPG and a PNG keeps its transparency through the resize. WebP is one tap away on the download button. The preview and the size in the card come from the actually encoded file, not an estimate.
The photo never leaves your device: resizing, previewing and saving all happen in your browser. No upload, no queue, no account, no watermark.
Open the image, type the width or height in pixels, and download. With the aspect lock on, typing one side calculates the other so the picture never distorts; unlock it to set both sides freely.
Making an image smaller always discards pixels, but how it is done decides how it looks. This tool uses Lanczos resampling, which preserves edges and fine detail far better than basic scaling, so the resized picture stays as sharp as its new size allows.
Yes. In Pixels mode type dimensions larger than the original, up to 10000 pixels per side. Enlarging cannot invent detail that was never captured, but the Lanczos interpolation keeps edges smooth instead of blocky, which is as good as honest upscaling gets.
Switch to Percent and tap how much smaller you want, 25, 50 or 75 percent, or set any custom reduction with the stepper. The line above always shows the exact resulting dimensions before you download.
Yes. Select or drop several images and the same settings apply to all of them; the result downloads as a single ZIP. Percent mode scales each picture relative to its own size, and a locked width keeps every image's own proportions.
No. The image is opened, resized and saved entirely in your browser. Nothing is transmitted to any server, which is also why even very large photos process quickly.
