Compress an Image Online — Free & Private
Large photos slow down websites, fill up storage, and make emails bounce. Photopik's compressor reduces file size while keeping your image looking sharp, using the same quality-controlled encoding professional tools rely on — and it happens entirely on your device, so nothing is ever uploaded.

Choose a fileHow it works
Drop in a JPG, PNG, or WEBP file, choose a quality level, and Photopik re-encodes the image right in your browser using the Canvas API. You'll see the estimated output size update live as you adjust the slider, so you can find the sweet spot between file size and visual quality before you download anything.
Frequently asked questions
Will compressing reduce the quality of my photo?+
Some quality is traded for file size — that's how compression works — but Photopik's encoder is tuned to keep compression artifacts minimal at moderate settings. Higher quality settings preserve more detail at a larger file size; lower settings shrink the file further with a visible but often acceptable quality trade-off.
What's the largest file I can compress?+
Since everything runs in your browser rather than on a server, the practical limit depends on your device's memory rather than any upload cap. Most photos, including modern smartphone camera images, compress without issue.
Is my photo uploaded anywhere?+
No. The entire compression process happens locally using your browser's built-in image APIs. Your file never leaves your device.
