Open your image and it is compressed to less than 300 KB, at or under the cap, automatically. The tool finds the highest quality that fits below the limit and reduces dimensions only when a huge photo cannot fit otherwise. The size card reports the original size, the new size and the saving, and the preview is the actually encoded output, so you can inspect the real result before downloading it.
A 300 KB cap gives a picture real room. Scanned certificates and mark sheets keep every line crisp, a product or property photo keeps texture and fine detail, and a portrait keeps natural skin at a generous size. It is a common limit on marketplace listings, membership portals, HR systems and any upload form that wants a JPG under 300 KB without turning it into a thumbnail.
If your form names another number, compress image to 150 KB, 200 KB, 500 KB or 1 MB instead; each page opens with its target set, and the presets carry the picture across. Any custom cap can be typed into the target box, and the Quality button swaps the target for a slider - the mode the main Compress Image tool opens in. The full compressor collection shows every size side by side.
A 300 KB JPG can be surprisingly large in pixels: a typical photo fits at 1400 to 1800 pixels on the long side, and a scanned page fits at full resolution. Only very large or very detailed images are scaled down, and only as much as needed.
Your photos and documents never leave your device. Opening, compressing and saving all happen in your browser, with no upload and no account.
Open the image and the tool automatically finds the highest quality that stays under 300 KB, scaling the dimensions only when the image is too large to fit otherwise. Check the preview and download; the size shown is the real encoded size, not an estimate.
Drop the photo here. It is saved as a JPG under 300 KB by default, whatever format it started in. WebP and PNG are one tap away on the download button.
Around 1400 to 1800 pixels on the long side for a typical photo, more for simple images and less for very detailed ones. The preview shows the exact result.
No. Compression happens entirely in your browser and the file saves straight back to your device. No server ever sees the image.
