which tool?
Choosing the right tool
- My photo gets cropped or looks blurry after posting
- Resize it to the platform's recommended size first with the Image Resizer, choosing Crop or Fit so the important parts stay in frame.
- My image is too large to upload or slows down my site
- Use the Image Compressor. Capping the width and using WebP or JPG at quality 70–80 usually cuts the size dramatically.
- An app won't accept my WebP or PNG file
- Convert it with the Image Converter. Choose JPG for maximum compatibility, or PNG to keep transparency.
- I need a thumbnail for a new video
- The YouTube Thumbnail Maker exports at 1280 × 720 or 4K with bold, outlined text and no watermark.
