When you need a 300 × 300 image
300 × 300 pixels is a small, square thumbnail size. You'll meet it as the size for profile pictures and avatars on forums, chat tools and company directories, for product thumbnails in online shops and catalogues, and on some application forms and portals that want a square photo of a set size. Each site sets its own rules, so check its help page or the upload screen for the exact numbers and the file types it accepts.
Because the square is small, a 300 × 300 JPG is usually only a few tens of KB. If the form also gives a limit in KB, resize first, then use the image compressor to get under it.
Crop to fill or fit inside
Most photos aren't square, so something has to give. Crop to fill keeps the centre of the photo and trims the longer sides until it's square. Fit inside keeps everything and shrinks the photo until its longer side is 300 px; with borders ticked, the rest of the square is filled with a colour.
| Original | Crop to fill trims | Fit inside gives |
|---|---|---|
| Landscape photo, 4:3, 1600 × 1200 | 200 px from each side | 300 × 225 px |
| Portrait photo, 3:4, 1200 × 1600 | 200 px from top and bottom | 225 × 300 px |
| Phone screenshot, 9:16, 1080 × 1920 | 420 px from top and bottom | 169 × 300 px |
| Square photo, 1080 × 1080 | Nothing, just scaled down | 300 × 300 px |
Use crop to fill for faces and scenes, where a full square looks best. Use fit inside with white borders for products, logos and screenshots, where cutting off an edge would lose something.
Keeping a face centred
Crop to fill always takes the middle of the picture. That works when the face is in the centre, but in a typical portrait the face sits in the upper part of the frame, so a centre crop of a tall photo can cut off the top of the head and keep too much of the shoulders.
For a profile photo, crop first: open Crop image, pick the 1:1 ratio, drag the square so the face sits in the middle with a little space above the head, and download. Then drop that square here; it's scaled to 300 × 300 with nothing more trimmed. Start from a photo at least 300 px on its shorter side so the result stays sharp.
Frequently asked questions
How do I resize an image to 300 × 300 without cropping it?
Choose Fit inside and tick the borders option. The whole photo is shrunk to fit in the square and the empty strips are filled with white, black or a colour you pick, so the file is exactly 300 × 300 px.
Will my photo be stretched or squashed?
No. Crop to fill trims the edges and Fit inside adds space, so the picture keeps its shape either way. If you really want to stretch it, switch to Pixels, untick Keep proportions and type 300 in both boxes.
What happens if my image is smaller than 300 × 300?
It is enlarged to fit, and the file row warns you by how much. Enlarging can't add detail, so a 150 px image made into 300 px looks soft. Start from the original photo if you have it.
Is 300 × 300 pixels the same as 300 DPI?
No. 300 × 300 is the number of pixels. DPI only says how large those pixels print: at 300 DPI a 300 × 300 px image prints 1 inch (2.54 cm) square. Screens and websites ignore DPI.
Can I resize many photos to 300 × 300 at once?
Yes. Drop them all in. Each one is cropped or fitted the same way, and Download all gives you a zip. Nothing is uploaded: the resizing happens in your browser.
