Best QualityHow it works: Exact-size compression
Shrinkly uses a specialized binary-search algorithm to find the highest possible image quality that fits within your target file size. Most compressors just guess; we test multiple quality levels in milliseconds to get you the best result.
Binary-Search Search Quality
We iterate through quality levels to find the perfect sweet spot for your 100KB or 500KB target.
Dimension Fallback
If your target is too small for the original resolution, we'll suggest or automatically adjust dimensions.
Frequently Asked Questions
Why compress to exactly 100KB?
Many government portals, school applications, and social platforms have strict file size limits. Shrinkly ensures you stay under the limit while keeping the best possible resolution.
Will my image lose quality?
Every compression involves some trade-off, but our binary-search algorithm ensures that we find the absolute mathematical peak of quality for your specific size target.
Is it safe to upload my photos?
Your photos are never uploaded. We use Web Workers and client-side processing to compress everything directly in your browser. Private and secure.
What formats are supported?
We support JPG, PNG, and WebP. You can convert between formats while resizing to further optimize your file size.
