Resize Image to 300×300 Pixels
300×300 is a workhorse size for avatars, icon drafts, and small product thumbnails. PNGful resizes your image to exactly these dimensions in your browser, showing you the result before you save it. The tool is free and your file is never uploaded.

Good to know
- 300×300 is square, so a landscape or portrait photo has to be either cropped to fill the square or fit inside it with padding. PNGful lets you choose, and cropping is usually the better look for avatars.
- If your source is smaller than 300×300, enlarging it cannot add detail — the result will be soft. Start from a larger original whenever possible.
- At small sizes, faces and logos read best when they fill most of the frame. Crop tighter than feels natural at full size.
- PNG keeps logos and text crisp at 300×300; JPEG or WebP is fine for photographic avatars and produces smaller files.

Frequently asked questions
Will my rectangular photo get distorted at 300×300?
No — PNGful never stretches your image. A non-square photo is either cropped to fill the 300×300 square or scaled to fit with padding added on two sides. You pick which, and you see the result before downloading.
Is 300×300 big enough for a profile picture?
For most forums and directories, yes, since they display avatars far smaller than that. For platforms that show profile photos large — or zoom them on click — a 500×500 or 800×800 version gives you more headroom.
Can I use a 300×300 image as an app icon?
As a draft or web icon, yes. For actual app store submissions, iOS and Android require larger masters (1024×1024 for the App Store), which get scaled down automatically. Design at the large size and use 300×300 for previews.
My image is 200×200 — can I resize it up to 300×300?
You can, but upscaling cannot create detail that was never captured, so expect some softness. For a small avatar the loss is often acceptable. If you have access to a larger original, resizing down from it will always look better.
Does resizing to 300×300 also reduce file size?
Almost always, and substantially. A 300×300 image contains a small fraction of the pixels of a camera photo, so files typically land in the tens of kilobytes. That makes this size doubly useful for forums with both dimension and file-size limits.
