Image Resizer
Resize by pixels or percentage with batch support.
Resize photos to exact pixel dimensions or scale them by percentage. Process one image or a whole batch at once — every file stays in your browser the entire time.
How to use the Image Resizer
- 1
Add your images
Drag photos onto the drop zone or click to browse. JPG, PNG, and WebP are all supported, and you can queue as many files as your device can comfortably hold in memory.
- 2
Pick a resize mode
Choose pixel dimensions when you need an exact width or height (for example, 1080×1080 for Instagram). Choose percentage when you want to shrink everything uniformly (for example, 50% of original).
- 3
Lock the aspect ratio
Leave the aspect-ratio lock on to preserve proportions automatically. Turn it off if you need a non-proportional result.
- 4
Download the result
Click Resize, then download each file individually or grab them all. The originals never leave your device — there is nothing to clean up server-side.

Frequently asked questions
Does resizing reduce image quality?
Downscaling (making images smaller) preserves quality well because you are discarding pixels. Upscaling (making them larger) is bounded by the original resolution — you cannot invent detail that was not there, so the result will look softer than the original.
Can I resize hundreds of images at once?
Yes, but memory is the practical limit. A modern laptop handles 20–50 photos at typical phone resolutions without trouble. For very large batches, process them in groups.
Will EXIF metadata be preserved?
The resize tool focuses on pixel data and does not preserve full EXIF. If you need to keep metadata, use the EXIF Viewer tool first to inspect what you have, then resize.
