智能压缩保持格式不变,或指定精确目标大小(如100KB)——输出保证不超过限制,专为报名表、证件照上传等有大小要求的场景设计。

Download compressed images, always under your limit
Reduce JPG, PNG or WebP file size in seconds. Smart mode keeps your format and picks the best quality-to-size trade-off. Exact-size mode guarantees the output stays under your limit (20 KB, 100 KB, 1 MB…) — built for forms and portals with hard upload caps that generic compressors can't hit.
Those tools compress 'as much as looks OK' with no size guarantee. Konomic adds an exact-size mode: tell it 50 KB and the output will be 50 KB or less — it finds the highest quality that fits, resizing only as a last resort. That's what form uploads with hard caps actually need.
Smart mode keeps it: JPG stays JPG, PNG stays PNG (palette-optimized), WebP stays WebP. Exact-size mode outputs JPG, since it's the only format where a precise size can be guaranteed. Transparency is flattened to white in that case.
Yes — 3 images per day without an account, 20 with a free account, up to 10 per batch, max 50 MB per file. No watermark on any plan.
Images are processed on EU servers (Germany), auto-deleted within 1 hour, and never used to train AI. Metadata (EXIF, GPS location) is stripped from the output — a privacy bonus.
One-click presets for the size limits forms actually ask for — output guaranteed under the cap.
