Image Resizer PCBatch resize an entire folder at once
Doing images one at a time is the slow, painful way — and most online tools force exactly that. Here you drop in a whole folder (or a big pile of files) and the app works through all of them in one go.
There's no cap on the number of files and nothing is uploaded, so it's just as happy with 5 images as with 500. Because it's a local Windows app, a large batch won't be throttled by your connection.
- Drag in folders or multi-select files
- No file-count limit
- Runs fully offline — a big batch never leaves your PC
- Choose one output folder for all results
One KB target applied to every image
This is the trick for bulk exam or job-application uploads where each photo must sit under a specific weight. Set a KB target once — say 50 KB — and the app fits every image to it, searching quality (and downscaling where needed) file by file.
Each image is fitted individually to land at or under the target, so a bright simple photo and a busy detailed one both come out under your limit even though they needed different settings.
Keeping a consistent look across the batch
When every image should look uniform — a wall of ID photos, a product grid — set exact pixels or a cm + DPI size and let the app center-crop each one to that same box. If you'd rather never crop, keep the aspect ratio instead and the app fits within your dimensions.
A fair warning: if your originals have very different shapes, "keep aspect ratio" will give slightly different final dimensions per image, while "center-crop to an exact box" guarantees identical size but trims the edges. Pick whichever the task needs.
- Same format for all (JPG, PNG, WebP, BMP)
- Center-crop to an exact box for identical dimensions
- Or keep aspect ratio to avoid cropping
