| Format | Width | Height | Notes |
|---|---|---|---|
| Photo JPG | 1600 | 900 | Use 70-85 quality for a strong size-to-quality balance. |
| Transparent PNG | 1200 | 1200 | Keep PNG only when transparency is required. |
| WebP web image | 1600 | 900 | Good choice for websites and downloadable assets. |
Quick answer
Compression is about removing unnecessary file weight while keeping the visible image clean. A good compressor should let you compare the original size and estimated export size before downloading. That matters because a photo that looks perfect at 90% quality may look almost identical at 78% while being much smaller.
JPG is usually the best format for photos. PNG is best for transparency, screenshots, and graphics with flat shapes. WebP often gives the smallest web files, but some workflows still require JPG or PNG. The right answer depends on where the image will be used.
Look at edges, gradients, faces, and text after compression. These areas reveal artifacts first. If text gets fuzzy or skin tones look blocky, raise quality or switch format. For most web and social images, start around 80% quality and adjust from there.
Recommended workflow
- Start with the largest clean source image you have.
- Choose the exact destination size before adding final text.
- Crop visually so the subject, logo, and key message stay inside the safe area.
- Export in JPG for photos, PNG for crisp graphics, or WebP for web use.
Checklist
- Resize before compressing when the source is oversized.
- Use JPG for photos and PNG for transparency.
- Check text and faces after export.
- Keep original files untouched for future edits.
