Description
Compress JPG, PNG, WebP and HEIC images to a chosen maximum file size in KB. Files are processed locally in the browser, with optional pixel resizing and individual or batch ZIP downloads. Free and no signup.
No-Login Task
"Compress images to a custom or preset KB limit, optionally resize dimensions, and download files individually or as a ZIP."
Editorial Review & Verification
Hands-on VerifiedJob applicants, visa candidates, students, and web developers who need to shrink photos under strict byte limits (such as 100KB, 50KB, or 20KB) directly in the browser without uploading private identification photos to cloud servers.
Sketching hand-drawn diagrams, architecture schematics, and interactive wireframes with client-side privacy.
+ Key Strengths (Pros)
- ✓ Zero registration required with instant drag-and-drop batch queue supporting JPEG, PNG, WebP, and HEIC files
- ✓ Iterative byte-exact constraint optimization targeting actual encoded size rather than rough compression percentage guesses
- ✓ Comprehensive privacy controls that automatically strip sensitive EXIF camera metadata on the local device
- ✓ Clean export pipeline generating a verified 99,204-byte ZIP archive meeting the exact sub-100KB requirement without watermarks
− Limitations (Cons)
- − Large multi-megapixel images require several iterative canvas encoding passes which consume local CPU cycles
Deep Privacy & Sandbox Audit & Product Power & Utility Review
Observed 3 internal form lifecycle GET triggers to origin (compressto100kb.com) with zero third-party telemetry or cloud uploads. Image scaling, iterative compression, and EXIF scrubbing execute entirely within local browser memory.
CADES 2.0 Route A dogfooding verified in ego-browser Chromium. Navigated to compressto100kb.com and uploaded an authentic 402.97 KB sample_large.jpg fixture. Clicked 'Compress images' with the 100 KB limit preset. The client-side iterative engine adjusted dimensions and encoding quality to produce a 99.85 KB output. Tested export trigger 'Download all (ZIP)', verifying a clean 99,204-byte archive artifact with zero watermarks or authentication gates.
