一键把照片压缩到30 KB或更小。与普通压缩工具不同，本工具保证输出不超过30 KB：算法自动寻找符合限制的最高质量，只有在万不得已时才缩小尺寸。常用于有大小上限的报名表、证件上传等场景。
Output guaranteed at 30 KB or less — highest quality that fits.

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.
能——这正是本工具的核心。算法通过二分查找找到30 KB以内的最高JPEG质量；若最低质量仍超标，则按比例缩小图片直到符合。绝不会超出限制。
工具总是选择30 KB限制内的最高质量。大照片压到很小的目标时会有可见压缩痕迹——这是物理极限，任何工具都一样。
免费：无账户每天3张，免费账户20张，单次最多10张。任何套餐都不加水印。
图片在欧盟（德国）服务器处理，一小时内自动删除，不用于AI训练。输出同时去除EXIF/GPS元数据。
