Free Online Image Compressor & Resizer
Compress, crop, resize and convert with precision—fully in your browser. Zero‑Upload mode delivers 100% on‑device privacy and works offline after first load. Target exact file sizes (1KB → 2MB) without sacrificing visual quality.
No Watermark

Exact KB Target
Why Choose ImgSmaller?
We focus on practical control: crop before compress, rotate if needed, set an exact target size, switch formats (JPG ↔ WEBP ↔ original) and export immediately—all with Zero‑Upload 100% privacy and offline capability. No accounts, no noise—just results you can trust.
Multi‑Image Workflow
Upload several images, fine‑tune each, then download individually or as a ZIP.
Quality Preservation
Edge-aware processing and color fidelity reduce artifacts in gradients & text.
Flexible Conversion
Switch to WEBP for smaller output or keep original extension for compatibility.
Private by Design
Zero‑Upload processing stays on‑device—nothing leaves your browser and it still works offline.
How It Works
A simple, three-step process to get perfectly sized images.
01
Upload Your Image
Upload or drag & drop one or multiple images (AVIF / JPG / PNG / WEBP).
02
Configure & Compress
Optional: crop & rotate for best framing. & Set a target size (or enable Auto quality).
03

- HTTPS enforced end‑to‑end
- Temporary storage auto‑deletion (server mode)
- Local canvas processing in Zero‑Upload
- Offline capable after first load
