Your images never leave your device. Compression happens directly inside your browser.

1500 × 500 px is the recommended X (Twitter) header size. Keep important content centered because edges are cropped on some screens.
Shrinker fits your image inside the 1500 × 500 box without stretching it. A 4000 × 3000 landscape photo becomes 666 × 500 px, while a 3024 × 4032 portrait becomes 375 × 500 px. If you need exactly 1500 × 500 with no empty edges, crop the source to 3:1 first.

Size estimates assume a typical photograph at good quality. Detailed or noisy images need more bytes; flat graphics need fewer.
Your photos hold moments, memories and sometimes sensitive details. That’s why compression happens on your device. Your images are not uploaded to our servers.
How we protect your privacyNot every image needs every byte. For JPG and WebP, we search for a quality level that fits your chosen size. If that’s not enough, we gradually reduce the dimensions, keeping the original proportions.
PNG works differently: its browser encoding is lossless. If your target needs a format change, you make that choice. You can always compare the preview and check the final size before downloading.
Everything you need to make
your next image a little lighter.
No. The image is scaled to fit inside 1500 × 500 px while keeping its own proportions, so only images with a 3:1 shape fill the box exactly. Crop first if you need an exact 1500 × 500 result.
No. Compression happens directly inside your browser on shrinker.app. Your images are not uploaded to our servers. Selecting, previewing and downloading use local files and browser Blob URLs.
Choose a preset or enter a custom size, then select Compress Image. For JPG and WebP, the tool searches quality settings and reduces dimensions if necessary. Check the result size before submitting it elsewhere. One KB in this tool equals 1,024 bytes.
JPG and WebP compression can lose detail. The tool tries to retain the highest quality that meets your target at each resolution. PNG encoding is lossless, although resizing a PNG still removes pixel detail. Always check the preview.
Canvas doesn't expose a lossy quality control for PNG. If lossless re-encoding can't reach your limit, choose an explicit conversion to WebP or JPG, or try larger target settings. WebP can preserve transparency; JPG uses a white background.
Yes. Use a current browser, choose a JPG, PNG or WebP image under 20 MB, and save the result to your device. Images above 40 megapixels or 16,384 pixels on either side are rejected to limit memory use.
