Frequently Asked Questions
- Which quality value should I use?
80 is the usual answer. At normal viewing size it is hard to tell apart from the original, and it typically removes more than half the bytes.
- Does compressing the same file twice help?
Barely, and it costs quality each pass. JPEG is lossy, so what a pass throws away cannot come back. Always start from the original.
- Is EXIF data kept?
No. The image is redrawn on a canvas before it is re-encoded, so camera model, timestamp and GPS coordinates do not survive.
- Do my files get uploaded anywhere?
No. This tool runs inside your browser tab. The file is read from disk locally and the result is written back locally, so there is nothing on our side to store or delete.
- Is there a size limit?
Images are capped at 100 megapixels, since the browser has to hold the full bitmap in memory. On file count: 8 operations per day without an account, 20 when signed in.
