Where a form states a range, open its page: it keeps the file above the minimum too. A size page only aims under the ceiling, so a file can come out too small.
What is the difference between resizing and compression?
The main difference between resizing and compression is the measurement you change. Resizing changes width and height in pixels. Compression reduces file size in bytes.
A photo can have the correct dimensions and still exceed an upload limit, so check both requirements.
If you need both, set the dimensions first and then adjust quality or the file size target. Work from the original and download once to avoid repeatedly recompressing a saved JPEG.
How far can you compress before it shows?
Start with a moderate quality setting and inspect the preview, especially faces, text and smooth backgrounds. Lower quality usually makes a smaller file, but there is no setting that looks equally good on every image.
JPEG suits photographs. PNG keeps sharp text and transparency but has no quality setting; fewer colours is what makes it smaller. WebP and AVIF offer alternatives; compare the actual output before choosing.

How to compress an image without losing quality, measured
What happens to your photo?
Your selected photo is processed in your browser, without an image upload to a server. The page may download code and codecs needed for editing.
Save your result before closing the tab; unsaved edits are kept in memory rather than in an online account.
Can I compress multiple images at once?
Yes. Add several photos and the compressor works on them as a batch. The quality or the target size in KB you set applies to every photo, and each keeps its own pixel size unless you change it.
Each photo gets a tile above the preview. Pick a tile to check the same settings on that photo before you commit. The results arrive one by one and download as one ZIP, and you can rename each file or number the whole batch.
Nothing is uploaded, and finished photos are kept on your device rather than in memory, so a hundred photos work as well as five. To resize a mixed folder by its longest edge, use the bulk image resizer.
Common questions
Does compressing change the dimensions?
No. Compression changes how many bytes describe the pixels, not how many pixels there are. The width and height stay exactly as they were unless you change them yourself.
How much can I compress before it looks bad?
The useful quality setting depends on your photo, output format and viewing size. Lower it gradually and inspect faces, text and smooth backgrounds.
Stop when artifacts become distracting, or reduce the dimensions if you still need a smaller file.
Why was a file under the limit rejected?
A form may count 1 KB as 1,000 bytes, where this tool and most computers count 1,024. A file shown here as 49.5 KB is 50,688 bytes, over a 50,000 byte limit. Aim a KB or two under.
A form with a range also rejects a file under its minimum, such as the 10 KB floor on an IBPS signature.
Is compression reversible?
Lossy exports discard detail that cannot be recovered by raising the quality later. PNG is lossless, but changing an already compressed photo to PNG will not restore missing detail.
Keep your original and use it for later edits.
Can I compress a photo on my phone?
Yes. Open this page in your phone's browser, tap Choose image and pick the photo from your library. An iPhone's HEIC photos open too.
The compression runs on the phone itself, so nothing is uploaded. On an iPhone the download lands in the Files app, under Downloads, rather than in Photos. On Android it goes to your Downloads folder.
How do I compress a batch of photos?
Add them all at once, set up one photo, and press Apply to all. Each photo is processed in your browser, one after another, and the results download as one ZIP. You can rename each file, or number the whole batch, before you download.
