Can I compress an image to exactly 100KB?

Yes. Set your target size in KB, the tool iteratively adjusts quality until the output is within 5% of your target. Works for JPEG and WebP.

Is compress-to-size lossless?

No. Reaching a target size requires reducing quality. PNG output is lossless only when target size allows it. JPEG/WebP always use lossy compression.

How accurate is the size match?

Within 5% of your target by default. The tool iteratively re-encodes with adjusted quality until the output falls in the acceptable range.

Does compress-to-size work on phone?

Yes. Mobile browsers (iOS Safari 14+, Chrome Android) handle the iterative encoding. Larger images may take a few seconds longer on phones.

What formats are supported?

JPEG, PNG, WebP, and GIF. Output is JPEG by default. For WebP output with smaller files, select WebP in the format dropdown.

Does it strip EXIF metadata?

By default, EXIF is stripped from output (privacy-first). To preserve EXIF, enable the 'Keep EXIF' toggle before compressing.

Can I batch compress to the same target size?

Yes. Drop multiple images, set one target size, and all are compressed in batch. Each maintains the same target KB.
