Settings questions
Percentage scaling shrinks relative to each image's size — ideal when sources vary. Pixel mode sets exact dimensions for specifications like banners or upload limits. The aspect-ratio lock keeps proportions correct in both modes; leave it on unless distortion is intentional.
All settings apply live to the whole batch: change a value and every card updates automatically. Experimentation costs nothing.
Quality questions
Downscaling rarely hurts visible quality — fewer pixels, same picture. Extreme reductions can soften fine detail slightly, so glance at critical images at their new size before publishing.
Upscaling is the opposite: enlarging invents pixels without adding detail, producing softness or blur. Avoid making images larger whenever possible; if you must, expect some softness and keep expectations modest.
Limits and practical questions
Up to 20 images per batch, processed automatically with per-image cards showing original and new dimensions. No accounts, no watermarks, no daily limits.
JPG, PNG, and WebP sources are supported. Downloads preserve file names, available individually or as one ZIP. Resizing runs entirely in your browser — nothing is uploaded.
After resizing
Pair resizing with compression for the leanest files: dimensions first, then bytes. A resized-then-compressed image is often a tenth of the original's size with no visible difference at its display size.
Keep originals archived. If a future design needs larger images, you will resize fresh from the masters rather than stretching the small versions — which never ends well.
Choosing quickly and pairing wisely
Still unsure which method to use? Default to 50% percentage scaling for general shrinking — it is the fastest path to a smaller image and behaves consistently across mixed sources. Switch to exact pixels only when a destination names a specific number. That single default resolves the decision paralysis most people feel when facing resize options for the first time.
Worried about quality? Downscaling is safe: the pixels removed are the ones nobody sees at the smaller size. The only genuine quality risks are upscaling, which you should avoid, and extreme reductions below 25%, which deserve a quick visual check.
And remember the pairing: resize for dimensions, then compress for bytes. The two tools together routinely turn a 5MB phone photo into a 150KB web-ready image — a 97% reduction with no visible difference at display size. Keep this page bookmarked: the next time an upload form rejects your image or a page loads slowly, the answer is usually one resize away. Small images, correctly sized, solve an outsized share of everyday web frustrations.
Frequently asked questions
Will resizing make my image blurry?
Downsizing: no, it stays sharp. Upsizing: yes, enlarging invents pixels and causes softness. Resize down freely; avoid resizing up.
How do I keep proportions correct?
Keep the aspect-ratio lock on — width and height scale together, so nothing stretches or squishes.
How many images can I resize at once?
Up to 20 per batch, each with a card showing original vs. new dimensions.
Are resized images uploaded anywhere?
No — resizing happens entirely in your browser. Your images never leave your device.
