Compress to a target size
Government portals, job sites and visa or university forms often reject photos above a set size such as 100 KB or 200 KB. In target size mode, the tool tries quality levels until the image fits under your limit at the highest quality possible. If the image still does not fit at the lowest sensible quality, it reduces the width and height step by step. Check the official photo rules for your form too, since many also set the pixel size and background colour.
Quality, format and what to expect
Photos from a modern phone are often 3 to 6 MB. Saved as JPG at 70% quality they usually become 300 KB to 1 MB and look the same on screen. WebP is roughly a quarter smaller again and suits websites and online shops, while JPG opens everywhere. PNG is lossless, so this tool converts PNG to JPG or WebP to shrink it; screenshots with sharp text can show slight blur at low quality. If a file is already well compressed, the original is kept rather than giving you a bigger file.
Private by design
Many online compressors upload your photos to their servers. This one uses your browser's own image encoder, so your pictures never leave your phone or computer. That matters for ID cards, passports, Emirates ID scans, invoices and family photos. The page keeps working even if your connection drops after it has loaded.
Limits
You can compress up to 50 images and 300 MB at a time. Very large images, such as 50-megapixel photos, can be slow on older phones. HEIC photos from iPhones open only in browsers that support them, such as Safari; if one fails, export it as JPG first. To change the pixel size instead of the file size, use the image resizer.
