Image Resizer & Compressor - JPG/PNG/WebP
What is an image resizer & compressor?
This tool scales images down to fit within max width/height, adjusts quality, and outputs JPG, PNG, or WebP. It’s ideal for web performance, social sharing, and quick previews.
How to use the image resizer
- Upload an image: JPG, PNG, WebP, or HEIC within the existing 10 MB cap.
- Set size: Enter max width/height; the image will fit inside those bounds while keeping aspect ratio.
- Pick format & quality: Choose WebP (default), JPG, or PNG; set quality (1–100).
- Download: Convert and save the optimized image.
Why use this resizer?
- Right-size images fast: Avoid oversized uploads for web and mobile.
- Format choice: Keep transparency (PNG/WebP) or shrink photos (JPG/WebP).
- Safety caps: Uses the same secure conversion API with size/dimension limits.
Use case 1: Social cover
Set 1920×1080, format WebP, quality ~80 for a sharp but lighter hero image.
Use case 2: Product thumbnails
Set 800×800 max, PNG/WebP if you need transparency; JPG if not.
Use case 3: Slide exports
Convert large PNGs to JPG at quality 70–80 to shrink decks for email.
Examples
- Transparent logo: Input PNG 2400×2400 → output WebP 800×800, transparency preserved.
- Photo: Input JPG 4000×3000 → output JPG 1600×1200 at quality 80, significantly smaller.
Common errors
File too large or dimensions too big
Stay within the 10 MB and 4096 px limits. Export a smaller source if needed.
Transparency lost
JPG cannot keep transparency. Choose PNG or WebP for transparent assets.
Tips and proven approaches
- Use WebP for most web images; fall back to PNG/JPG only for compatibility.
- Lower quality gradually (e.g., 90 → 80 → 70) while spot-checking artifacts.
- Keep aspect ratio intact by setting max width/height rather than exact forced sizes.
