Check each image, its dimensions and file size before downloading.
The 1MB preset leaves more room for detailed photos. Output may still be lossy or lower in resolution; compare it with the original, then decide whether it fits the destination’s requirements. This preset uses 1 MiB (1,048,576 bytes). If the destination uses decimal KB/MB, check its byte cap and use a lower custom target.
1MB does not mean lossless
Lossy encoding discards information and resizing removes pixels. A 1MB file does not prove that faces, text or landscape textures were preserved unchanged; compare with the original at the intended viewing size.
When to use 1MB
If the destination allows a larger image and the 500KB output loses important detail, compare a 1MB result. For printing, enlargement or later editing, keep the high-resolution original rather than making the compressed copy your only archive.
Frequently asked questions
It can. Lossy encoding and downscaling can alter detail, and file size cannot guarantee quality. Check small text, faces, fine lines and color transitions, and retain the original.
Start with the destination’s actual byte cap. A larger target may preserve more detail, but compare the outputs. The 1MB and 2MB presets use 1 MiB and 2 MiB, which differ from decimal MB.
No. Compression runs locally in your browser, files are never uploaded, and it's free with no file-count limit.
