Resize Image to 300x300 Pixels

300×300 pixels is one of the most requested square sizes on the web. WordPress creates a 300 × 300 "medium" copy of every upload by default, many shop themes show product cards at about 300 px, and a lot of job portals, school systems and membership sites ask for a 300 × 300 profile photo. It is also a safe minimum for profile pictures on social networks that display them at 100 to 200 px.

A 300 × 300 image holds 90,000 pixels (0.09 MP). Saved as a JPG at the default 90% quality, a typical photo at this size weighs roughly 15 to 35 KB; logos and flat graphics are usually lighter. In print, 300 pixels span 1 in (2.5 cm) at 300 DPI, or 2 in (5.1 cm) at 150 DPI.

What 300 × 300 pixels is used for

• WordPress medium size: matches the default medium image (300 × 300 max) used in posts and galleries.
• Profile photos on forms: job portals, school, exam and membership sites that ask for a 300 × 300 photo.
• Product cards: category grids and "you may also like" blocks in online shops.
• Spotify and podcast tools: a safe minimum for playlist covers and small cover thumbnails.

How to resize an image to 300 × 300 pixels

1. Drop your images on the box, click to choose them, or paste one with Ctrl+V (JPG, PNG, WebP, AVIF, HEIC, GIF, BMP, TIFF, SVG; up to 80 MB each).
2. The size is preset to 300 × 300 px with Crop to fill; choose which part to keep (center, top, bottom, left or right) or switch to Fit with background or Stretch.
3. Pick the format: Original, JPG, PNG, WebP or AVIF (in browsers that can encode it), and set the quality, or switch to Target size and enter a limit in KB.
4. Drag the before/after slider on the preview; every change is re-rendered live.
5. Click Download, or Download all (ZIP) for several files, named like photo-300x300.jpg.

Turning a non-square photo into 300 × 300

Phone and camera photos are usually 4:3 or 3:2, so a square needs a decision. Take a 4000 × 3000 shot: Crop to fill scales it to 400 × 300 and trims about 50 px from the left and right edges. Fit with background keeps the whole picture at 300 × 225 and fills 38 px above and below with white, black, grey, any colour or transparency (PNG, WebP, AVIF). Stretch squeezes it to 300 × 300, which distorts faces, so keep it for images that are almost square already. With Fit, the Don't enlarge smaller images option centres a small source at its own size instead of blowing it up.

Tips for 300 × 300 images

• Use the Top position for head-and-shoulders portraits so the crop never cuts off the head.
• If the site shows the photo in a circle, keep the face in the middle third: the corners are hidden.
• Forms that ask for 300 × 300 often limit the file to 50 to 100 KB too; Target size handles both at once.

Everything runs in your browser: images are never uploaded, and there is no account, no watermark and no limit on the number of files. Under More options you can write a DPI value into JPG and PNG files or change the file-name pattern, and location and camera data (EXIF) are always removed.
