Why quality matters

Smaller.
Same as you see it.

Quality 80–90 is visually lossless for most photos and graphics. Below 75 you save more, but you trade looks.

Near-lossless

Lose bytes, not looks.

80–90 keeps visible quality while cutting 30–60% of bytes. Below 75 you save more but trade clarity — you pick the tradeoff per batch.

FAQ

Without losing quality — FAQ

Is lossless vs near-lossless different?

Lossless keeps every byte — small savings. Near-lossless 80–90 throws invisible data — 40–60% smaller and still looks the same. For photos, near-lossless wins.

02
What quality keeps looks?

85 is visually lossless for most photos. 80 is still lossless to the eye for web. 90+ for archival where you keep more bytes.

03
Can I re-compress already compressed images?

Yes, but savings are smaller the second time. For best quality, compress from the original, not a prior export.

Do I need to upload?

No. All compression is local. No upload, no account.
