Image Shrinker

Shrink a whole folder of images in one pass: resize, re-encode to JPEG or WebP, pull images out of a ZIP, and move exact duplicates and originals aside so nothing is lost.

Built for the folder you have been avoiding — 300 screenshots, a camera card dump, or an AI batch that came back at 4K when you needed 1080p. It runs offline on your own machine and touches nothing you did not give it.

The Image Shrinker window: a thumbnail list of five photos on the left, a preview pane on the right, and output options below — Image Shrinker 1.0 on Linux, five images loaded and one selected.

The problem

Most free options handle one image at a time. When the job is a folder of three hundred, the tool is the bottleneck: open, resize, save, repeat — then work out by hand which files were duplicates.

What it does

Add a folder, a list of files, or drag them onto the window — nothing is scanned behind your back
Pull every image out of a ZIP, flattened, with collision-safe names and non-images skipped
Resize to 25, 50, 75 or 100 % with LANCZOS resampling; output JPEG or WebP with four quality presets
Originals move into their own folder so nothing is destroyed, or stay put if you only want copies
Exact duplicates found by SHA-256 and moved aside safely, never overwritten
Live progress and a report at the end: “412 MB → 38 MB, 91 % smaller”
Remembers the last folder, presets and window size between sessions

The window

Image Shrinker with five photos listed, sizes in KB, one image previewed, and the output options set to 75 percent, JPEG, high quality — Add, sort, preview, then shrink the batch

How buying works

One purchase, one key, three activations — so your laptop and desktop are both covered. The trial caps at 100 images, with no timer and no watermark; a key lifts the cap for good.

Pay once at checkout, and the license key arrives with your receipt
Paste the key into the app’s license dialog; the status in the header turns from a trial count to “Licensed”
Activation is stored on the machine, so the app keeps working offline; a lapsed connection never locks you out
Lifetime for 1.x updates, including fixes

Requirements and fine print

Windows 10 or 11 on x64, or Linux on x64 (AppImage runs without installing). No internet connection is needed after activation. The app moves original files into an Originals folder as it works, so keep a backup of anything irreplaceable. macOS is not supported yet.
