Does my image get uploaded?

No. All compression happens locally in your browser using the Canvas API. Your files never leave your device and are never sent to a server.

Does compression reduce quality?

Lossy formats (JPG, WebP, AVIF) trade a little quality for much smaller files, and the quality slider lets you find the right balance. PNG is lossless, so it stays pixel-perfect.

Which formats are supported?

You can compress JPG, PNG and WebP. You can also convert a PNG photo to WebP during compression for much smaller files.

Can I compress to a specific file size?

Yes. Switch to “Target size” mode and PixelVault searches for the highest quality that fits under your chosen KB limit.

Can I compress multiple images at once?

Yes. Drop in as many images as you like and download them individually or together as a single ZIP file.

Compress an image to 500KB

Bring larger photos under 500KB without visible quality loss. Target-size mode picks the best quality that fits, entirely in your browser.

Privacy-first: every image is processed locally in your browser. Nothing is uploaded, stored or transmitted to any server.

A comfortable budget for real photos

500KB is the roomy end of upload limits — portfolio sites, property listings, CMS media libraries and document systems. A full-HD (1920px) photo fits under 500KB at quality most people cannot distinguish from the original, so this target is less about sacrifice and more about predictability: every file reliably under the line.

Batch consistency without babysitting

Point a whole shoot at the 500KB target and each image is individually optimized to the best quality that fits — large photos compressed more, small ones barely touched. The comparison slider verifies any single result, and the ZIP download collects the lot. Local processing means originals never leave your machine.
