Resize Image to 350x350 Pixels

350×350 pixels is a practical in-between size for website layouts: large enough to fill a card or sidebar widget on a desktop screen, small enough to load instantly on mobile. Blog themes, portfolio grids and shop category pages often display square images at 320 to 360 px, so a 350 px square fits them without the browser having to scale it much. It is also a common requirement in online application forms that ask for a slightly larger photo than 300 × 300.

A 350 × 350 image holds 122,500 pixels (0.12 MP). Saved as a JPG at the default 90% quality, a typical photo at this size weighs roughly 20 to 50 KB; logos and flat graphics are usually lighter. In print, 350 pixels span 1.17 in (3 cm) at 300 DPI, or 2.33 in (5.9 cm) at 150 DPI.

What 350 × 350 pixels is used for

• Blog and portfolio cards: square cover images in three- or four-column grids.
• Sidebar widgets: author boxes, featured products and "about me" photos.
• Product category pages: square product shots in shop themes with ~350 px cards.
• Application forms: portals that ask for a 350 × 350 photo or logo.

How to resize an image to 350 × 350 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 350 × 350 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-350x350.jpg.

Turning a non-square photo into 350 × 350

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 467 × 350 and trims about 58 px from the left and right edges. Fit with background keeps the whole picture at 350 × 263 and fills 44 px above and below with white, black, grey, any colour or transparency (PNG, WebP, AVIF). Stretch squeezes it to 350 × 350, 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 350 × 350 images

• Check the size your theme actually displays (right-click the image → Inspect); if it is shown at 350 CSS px on retina screens, export 700×700.
• Keep all images in one grid the same size and crop position, so the cards line up perfectly.
• For grids with many images, choose WebP: it is typically 25 to 35% smaller than JPG at the same quality.

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.
