Reduce Image Size Without Losing Quality
Cut your file size down while keeping the image visually sharp.

Can you really reduce size without losing quality?
Honest answer: JPEG compression is lossy, so some data is always discarded. But between roughly 75% and 95% quality, the data being discarded is detail your eye cannot resolve on a screen — the file gets dramatically smaller while looking identical. That is the range this tool works in. When it needs to go further it reduces dimensions rather than pushing quality down into the range where blocking and colour banding appear. If you need genuinely lossless output, PNG and WEBP lossless will deliver it, but expect files several times larger.
What to expect at 500KB
What actually happens to different kinds of image:
| Starting file | Typical result |
|---|---|
| 12MP phone photo (around 5MB) | around 500KB at full dimensions — no visible difference |
| Screenshot containing text | stays crisp, but check it at 100% zoom |
| Graphic with flat colour or gradients | better kept as PNG or WEBP — JPEG bands gradients |
The honest test: open the original and the result side by side at 100% zoom. If you cannot tell them apart, no quality that matters was lost.
How it works
- Select your file using the box above — it stays on your device.
- We compress it in your browser, adjusting quality and dimensions until it fits under 500KB.
- Download the result — your original file never leaves your device.
What to do next
- If the image is larger on screen than it needs to be, resizing beats compressing every time. Compress Image for Website →
Frequently asked questions
So is 'without losing quality' just marketing?
Largely, yes — when a site says it, it means without losing quality you would notice. Truly lossless compression exists, but it saves far less: typically 5–20% rather than 80%.
Which parts of an image suffer first?
Sharp edges against flat backgrounds — text, logos, line art — and smooth gradients such as skies, which develop visible bands. Detailed natural scenes hide compression best of all.
What quality percentage should I aim for?
85% is the usual sweet spot for photographs. Below 75% artefacts start becoming visible; above 95% file size climbs steeply in exchange for detail nobody sees.
Is it better to resize or to compress?
Resize first if the image is larger than it needs to be. Halving the dimensions removes 75% of the pixels, which saves far more than any quality setting — and costs no visible quality at all if the image was oversized to begin with.
Does repeated compression damage an image?
Yes. Each JPEG save discards more data and the losses accumulate. Always start from the original file rather than re-compressing a compressed copy.
