Compress Image

Drop an image onto this page, choose a quality level with the slider, and click Compress and download. The image is re-encoded as a smaller JPEG in your browser and downloaded instantly — nothing is uploaded and there is no watermark.

No. Unlike most online compressors, this one runs entirely in your browser. Your image is never sent to a server, stored, or shared, and once the page has loaded it even works offline.

80% is the sweet spot for most photos — a big size reduction with no visible difference at normal viewing. Use 90% for photos you care deeply about, and 60–70% for email attachments and web pages where size matters most.

It depends on the source. Camera JPEGs typically shrink 40–70% at quality 80; PNG photos often shrink 80–90% when converted to JPEG. The exact before and after sizes are shown after compressing, so you can adjust and retry.

JPEG compression is lossy, so some detail is technically discarded — but at 80% quality the difference is invisible for normal viewing. The dimensions stay exactly the same; only the file size drops.

No — compressing keeps the pixel dimensions identical and only reduces the file size. To make the image smaller in pixels too, use the Resize Image tool on this site; combining both gives the smallest files.

It is removed. Compression re-encodes the image, producing a clean file without the original's hidden metadata — including any GPS location — which also saves a little extra space.

Yes — it is converted to a JPEG, which is dramatically smaller for photographs. Note that JPEG has no transparency: transparent areas are flattened onto white. For graphics that must stay PNG, keep the original.

Smaller images upload faster, fit email attachment limits, load web pages quicker, and take less storage. A phone photo of 4–8 MB typically becomes 1–2 MB with no visible difference.

Yes, completely free, with no account, no watermark, and no upload. For photo metadata tools on iPhone and iPad, the EXIF Viewer by Fluntro app is a one-time purchase.
