A common size before uploading
A back office requires images no wider than 1920; run a whole folder of photos through “limit longest edge 1920” in one go.

Guide
Resize Images scales a batch of images to a common target size: enter a width or a height in pixels, scale everything by a percentage, or cap only the longest edge at a value with the other side computed proportionally. Scaling uses pica's high-quality resampling (quality 3), so downscaled edges do not go soft; the processing happens locally in the browser and images are never uploaded.

The difference from “Image Compress” is that compression lowers the encoding quality without touching pixels, while this changes the pixel dimensions; compared with the workbench's “Image Crop and Rotate”, it cuts nothing away, previews nothing per image, and runs one set of parameters across many images in one pass.
_widthxheight suffix and can be downloaded individually or packaged as a zip.A 4000×3000 JPG, by pixels, width 1920, lock ratio on
→ 1920×1440, file named `xxx_1920x1440.jpg`
A 6000×4000 landscape and a 3000×4500 portrait, longest edge 2000
→ 2000×1333 and 1333×2000 (each scaled by its own long side)
An 800×600 PNG, longest edge 1920, do not enlarge, on

Scale a whole set of product images by 25% to use as list-page thumbnails.
Scale a 40-megapixel original to a 2000 px longest edge before sending it to a group — still clear, without the data cost.
Turn the ratio lock off, enter 1000×1000, and pull assets of different ratios into one square size (it distorts, so it suits texture-like material).
Downscaling uses pica's multi-step resampling, which is sharper than the browser's default scaling. Upscaling cannot create new detail, though — use “Photo Restoration” to make a small image clearer.
“Do not enlarge small images” was on and the original was smaller than the target, or the target happened to equal the original; the note in the result list says which.
No — redrawing on a canvas discards all metadata. If the shooting parameters need recording, look them up with “EXIF Viewer and Remover” before resizing.
Scaling is done locally in the browser with canvas and pica and images are never uploaded to any server; temporary files are released from memory when the page is closed.

Batch-scale by pixels, percentage or longest side with high-quality pica resampling
Uses pica for high-quality resampling, so downscaled images stay sharp
With the ratio locked you can fill in one side only; with both filled, the image is scaled down proportionally to fit. Unlocked, the image is stretched to the exact width and height.
