Resize image to 50% — instantly
Phone cameras shoot 12 megapixels and up, but most uploads, blogs, and screens need a fraction of that. Halving an image to 50% quarters its pixels and typically cuts 60–80% of the file weight — while staying razor sharp. The resizer below opens pre-set to 50% with aspect lock on: drop a photo, hit Resize, download. No uploads, no accounts.
How to halve your image
- 1Drop your image on the tool above. Percent mode at 50% is already selected.
- 2Optionally pick a format. Keep preserves the original; WebP shrinks it further.
- 3Hit Resize and download. The filename includes the new dimensions, e.g. photo-2000x1500.jpg.
Why 50% is the magic number
Quarter the pixels
50% width × 50% height = 25% of pixels. Oversized originals shed most of their weight in one click.
Still plenty sharp
A 4000px photo becomes 2000px — still sharper than nearly every screen, feed, and slideshow needs.
Need exact KB instead?
Pair it with compression: halve first, then hit an exact target with our 100KB compressor.
Frequently asked questions
Does 50% mean half the quality?
No — 50% refers to width and height, not quality. Sharpness per pixel is preserved; there are simply fewer pixels.
Will it stay sharp?
Yes. Downscaling with high-quality resampling keeps detail beautifully — a halved 4000px photo still exceeds most needs.
How much smaller will the file get?
Typically 60–80% smaller, since pixels quarter. Combine with WebP output for maximum savings.
Is the aspect ratio preserved?
Yes — aspect lock is on by default, so nothing stretches. Prefer exact pixels? Switch to PX mode in the full resizer.
Are my images uploaded?
No. Resizing runs 100% in your browser — files never leave your device.
