How to Compress Images Without Losing Quality
Updated July 2026 · KeepClip
A photo straight off a modern phone camera is often 4–8MB. That is far more data than any website, email or upload form actually needs, and oversized images are the single most common reason web pages load slowly.
Compression usually cuts that to a few hundred kilobytes with no difference you can see. Here is how to do it properly, and how to pick the right settings.

Step by step
- 1
Open the compressor
Go to keepclip.live/image-compressor.
- 2
Add your image
Drag a JPEG, PNG or WebP into the box, or tap to pick one from your device.
- 3
Choose format and quality
Pick WebP or JPEG, then set the quality slider — 80% is a good default.
- 4
Compress and download
Press Compress and save the smaller file. You will see exactly how much space you saved.
What quality setting should you use?
- 80% — the sweet spot. Visually identical to the original for almost all photos, typically 60–80% smaller.
- 60–70% — for web images where speed matters more than perfection. Slight softening in fine detail.
- 90%+ — for print, portfolios, or images that will be edited further.
- Below 50% — only when you truly need the tiniest file. Compression artefacts become visible.
JPEG, WebP or PNG — which to pick?
WebP is the best default for the web. It produces files roughly 25–30% smaller than JPEG at the same visual quality, and every modern browser supports it.
JPEG is the safe universal choice — pick it when the file needs to work with older software, or when an upload form specifically requires .jpg.
PNG should only be used when you need a transparent background or you are compressing a screenshot with sharp text and flat colour. For photographs, PNG produces much bigger files for no visual benefit — converting a PNG photo to JPEG or WebP is often where the biggest savings come from.
Common size limits worth knowing
- YouTube thumbnails — 2MB maximum. A compressed JPEG comfortably fits.
- Gmail attachments — 25MB total across all files.
- Most job application portals — 1–2MB per document or photo.
- Website images — aim for under 200KB per image for fast loading.
Why in-browser compression is safer
Most online compressors upload your photo to their servers, which means handing your personal images to a company you know nothing about. This one runs entirely inside your browser using the standard canvas API, so the image never leaves your device.
That also makes it instant — there is no upload wait, no queue and no processing server to be busy.
Frequently asked questions
Will compressing damage my photo?+
At 80% quality the difference is invisible to the eye for almost all photos, while the file gets dramatically smaller. Only very low settings cause visible artefacts.
Is my image uploaded anywhere?+
No. Compression happens entirely in your browser — the file never reaches a server.
What is the difference between compressing and resizing?+
Compressing reduces file size while keeping the same dimensions. Resizing changes the pixel dimensions. For most upload limits, compressing is enough.
Can I compress a PNG?+
Yes. For photographs, converting the PNG to JPEG or WebP while compressing usually gives by far the biggest saving.
Is there a file size limit?+
Images up to 50MB work fine, and you can compress as many as you like for free.
