Compressing…—
Re-encoding did not make this image smaller: it was already compressed efficiently. Try WebP or a lower quality, or keep the original.
The original still contains its metadata.
Camera details, GPS location and other metadata are removed from the compressed copy.
Tips
- Which format? WebP is usually the smallest at the same visual quality and keeps transparency. JPEG opens everywhere, even in older software. PNG is lossless: right for screenshots and diagrams, but a re-encoded PNG is rarely smaller than the original.
- Finding the quality. Start at 75, switch to 1:1 and move the divider across edges, skies and text: blocky patches and halos show up there first. Lower the quality until you notice them, then go back up a step.
- Resize before you compress. The pixel count grows with the square of the side: halving the width and height leaves only a quarter of the pixels. 1920 px is enough for a full-screen photo on most displays; 1280 px suits email and chat.
- Keyboard. Paste an image with Ctrl V (⌘ V on a Mac). The divider and quality sliders move with the arrow keys; Home and End jump to the ends.
- What is removed. The compressed copy carries no EXIF data: no camera model, capture time or GPS location. Colors are converted to sRGB, the standard color space of the web.
- Large photos on phones and tablets. On these devices the tool works within a canvas of at most 16,777,216 pixels (4096 × 4096), the largest that iOS Safari allows. Larger photos are scaled down to fit, and the tool tells you when that happens.
