JPG / PNG / WebP — files never upload
A casual phone photo is several megabytes; uploading it as-is slows your page, tests visitors' patience and hurts SEO — and many forums, forms and admin panels cap upload size anyway. Compressing first often shrinks a file to 20–30% of the original with no visible difference, saving a lot of bandwidth and waiting.
This tool compresses inside your browser; images are never uploaded to a server, which is reassuring for screenshots, IDs or photos of contracts that contain personal data. It works offline too — process and download, with no worry about files lingering on someone else's host.
For the web, visually-lossless is usually plenty; for print or client work, compare the download with the original so you don't blur important detail. Need smaller? Drop the quality a touch or reduce the dimensions — 1200–1600px wide is ample for article images. Pairing with our social image size guide helps for posts.
Small files are not the only goal; the useful balance is clarity, dimensions, format and upload limits.
Many phone photos are 3000-6000px wide, while article images rarely need that. Reducing the max edge to 1600 or 1200px before lowering quality is usually clearer than crushing quality alone.
Photos are usually smaller as JPG or WebP. Logos, screenshots and text-heavy images stay sharper as PNG. If your CMS or platform rejects WebP, export JPG/PNG to avoid upload failures.
After compression, zoom into text edges, faces, product texture and gradients. Saving 80% is not useful if text turns blurry; saving 40% with no visible loss is often a better result.
This tool runs in your browser and does not upload images. Very large images or many files at once are limited by your device memory; if the browser slows down, process in smaller batches.
No. This tool runs entirely in your browser — your images never leave your device, so it's completely private.
JPG, PNG and WebP, and you can convert the output format while compressing.
Because it runs locally, the limit depends on your device memory. Images of tens of MB usually work fine.
