Three ways to fit an image into 300×300
Most photos are not square — phone pictures are usually 4:3 or 16:9. To turn them into a 300×300 image, you need to decide what happens with the extra space. This tool gives you three options:
- Crop to fill — the image is scaled to cover the whole square and the edges are trimmed. Use the position sliders to choose which part stays visible. Best for avatars and thumbnails.
- Fit inside — the whole image stays visible and the empty space is filled with a colour you choose. Best for logos and product photos. For a blurred background, use make image square without cropping.
- Stretch — the image is forced into the new shape. This distorts proportions, so use it only for patterns or textures.
Where is 300×300 used?
300×300 pixels is a popular size for profile pictures, forum avatars, product thumbnails, app store icons in some catalogues and photos in online application forms. It is small enough to load quickly and large enough to look sharp on most screens.
Sharp results when shrinking big photos
Reducing a 4000‑pixel photo directly to 300 pixels can produce jagged edges. Our resizer reduces images in several halving steps with high-quality smoothing, which keeps lines and text noticeably cleaner than a single-step resize.
Need a specific file size too? After resizing, use compress to 20KB or reduce image size in KB.
