Features
Instant, right in your browser
The JPEG engine runs in your browser. A 6 MB photo resizes in well under a second with no progress bar to watch.
EXIF-safe and watermark-free
Orientation is applied to the pixels so portraits stay upright, and your download carries no badge, stamp, or overlay.
Resize a JPG in three steps
Drop your JPG
Drag a JPG or JPEG in, tap to pick one on your phone, or paste from the clipboard. It loads instantly and stays on your device.
Set size and quality
Type exact pixels or a KB target, then drag the quality slider while the preview updates. Find the smallest file that still looks right.
Download the JPG
Save the resized JPG with a clear filename. The original is untouched on disk because it never left your device.
Common JPG resize jobs
Shrink a camera JPG for the web
A 24-megapixel JPG is far bigger than any web page needs. Pull it to 1920 wide at quality 85 and the file drops from megabytes to a few hundred KB with no visible loss.
Resize a JPG photo for a profile
Most profile slots want a square around 400×400. Drop your JPG, tap the square preset, and download — sized right on the first try.
Fit a JPG under an email limit
Inboxes cap attachments around 25 MB. A 1280×720 JPG at quality 80 lands well under that and still looks clean in the preview pane.
Resize JPGs for a marketplace listing
Etsy, eBay, and Depop set minimum and maximum sizes. A 2000×2000 JPG at quality 85 satisfies almost every storefront and uploads fast.
Compress a JPG to a portal's KB cap
Visa sites and DMV forms often demand under 200 KB. Switch to KB-target mode, type the cap, and the output lands inside the limit automatically.
Resize scanned JPG documents
Scans come out huge. Resize to a sensible width and a moderate quality so the text stays readable while the file becomes easy to attach.
Resizing a JPG without wrecking it
JPG is a lossy format, which means every time it is saved it throws away a little detail to stay small. Resize it carelessly — at low quality, with the wrong resampling — and you get muddy edges, blocky skies, and the speckly halos around text that photographers call artifacts. A good JPG resizer is mostly about *not* doing that.
AnyResizer downscales JPGs with Lanczos resampling, which keeps edges crisp instead of soft, then re-encodes at a quality level you choose with a live slider. You see the trade-off as you drag it: smaller file on the left, sharper photo on the right. The default of 85 is the sweet spot most photos want, but you are never locked into it.
The whole job runs inside your browser tab on a WebAssembly engine — the same JPEG library desktop tools lean on. Your photo stays on your device, so there is no wait and no daily cap. EXIF orientation is baked into the pixels so a portrait shot never flips sideways, and you can target an exact KB ceiling when a form demands one.
Why resize JPGs here
- Live quality slider with instant previewDrag from 1 to 100 and watch the photo and the estimated file size react in real time — no guesswork.
- Exact pixels or exact KBType a width and height, or switch to KB-target mode and let a binary search hit a 200 KB or 1 MB cap for you.
- Lanczos resamplingSharper downscales than the bilinear shortcut most quick tools use, so detail survives the shrink.
- Batch a folder of JPGsDrop many at once, apply one setting, and download the whole set zipped in a single click.
Tips for sharper JPGs
- Tip 1:
Quality 85 is the photographer's default — visually lossless for most photos while cutting the file substantially. Drop below 70 only when size truly matters more than detail.
- Tip 2:
Never up-size a JPG and expect detail to appear; enlarging only stretches the pixels you already have and exaggerates artifacts.
- Tip 3:
If your image has hard edges, text, or transparency, JPG is the wrong format — use PNG or WebP instead. JPG shines on photographs.
- Tip 4:
Each re-save of a JPG loses a little more. Resize from the original whenever you can rather than re-editing an already-compressed copy.
- Tip 5:
For email, 1280×720 at quality 80 is a reliable target that previews cleanly and inline-renders in most clients.
Resize JPG FAQ
How do I resize a JPG online?
Drop your JPG into the box at the top, type a width and height or a KB target, drag the quality slider, and click download. There is no account, no install, and no plugin.
Can I resize a JPG without losing quality?
JPG is lossy, so a resize is never perfectly lossless, but at quality 85 with Lanczos resampling the loss is invisible to the eye. For truly lossless output you would need to convert to PNG or lossless WebP — also available here.
Does resizing a JPG make the file smaller?
Yes. Fewer pixels plus re-encoding at a sensible quality usually cuts a multi-megabyte photo down to a few hundred KB. You can watch the estimated size update as you adjust the slider.
Will my JPG be uploaded to a server?
No. The JPEG engine runs in your browser with WebAssembly, so the file never leaves your device. You can confirm nothing is sent in your browser's Network panel.
Can I resize a JPG to an exact KB size?
Yes. Switch to KB-target mode, type a cap like 100 KB or 1 MB, and a binary search across dimensions and quality lands the output within about five percent of your target.
Why does my resized JPG look blocky?
That is JPEG artifacting from too-low quality. Raise the quality slider, and if the source was already heavily compressed, start from a cleaner original — re-compressing a bad JPG only adds more blocks.
Does the resized JPG keep its EXIF data?
Orientation is applied to the pixels so the photo stays upright everywhere. Other EXIF metadata is dropped by default to keep the file lean and private; the visible image is unchanged.
Can I resize several JPGs at once?
Yes. Drop multiple files, set one size and quality, and download the whole batch as a ZIP in a single pass.
