Resize image

Enter a width and height in pixels, choose a percentage or use a preset, then preview and download the resized image. Application portals may ask for a 300 × 300 or 600 × 600 photo, marketplaces want product images at a set width, and profiles often need a square crop. You can resize several images at once.

• Making a photo or signature match the pixel size an exam or visa form states.
• Scaling product photos to one consistent width for an online shop.
• Shrinking large camera photos so they load quickly on a website or in email.
• Rendering an SVG logo to a PNG at a specific size.

With the aspect ratio locked, enter a width or a height and the other side is calculated so nothing looks stretched. Unlock it when a form requires an exact width and height; if your photo is a different shape, Crop to fill trims the edges evenly so faces aren't squashed. The 25%, 50% and 75% presets are quick ways to cut size; 2× doubles the dimensions.

• Form gives both width and height? Unlock the ratio, enter both, and keep Crop to fill on. Crop first only if you want to pick what gets cut.
• Only need a smaller file? Reduce width to 1600–2000 px; most photos still look sharp on screens.
• You can change the output format and quality here, so resizing and compressing can happen in one step.

Making a small image bigger spreads the same pixels further, so it looks soft; start from the largest original you have. Very large targets are limited to 80 megapixels to protect browser memory. SVG files are rendered to pixels, so choose the final size here rather than enlarging the PNG later.

• Confirm the result shows the exact width × height the form asked for.
• Check the file size too; a correctly sized image can still exceed a KB limit.
• If the shape changed, check that Crop to fill kept the part of the photo you wanted.
• Forms that give a size in cm at a DPI want pixels: 3.5 × 4.5 cm at 300 DPI is 413 × 531 pixels (cm ÷ 2.54 × DPI).

The exact sizes forms and platforms ask for most often. Enter both numbers with the aspect ratio unlocked. Platforms revise their recommendations, so check the current guidance for anything official.

• 600 × 600: US passport and visa photo upload (DS-160), and many profile photos.
• 413 × 531: a 35 × 45 mm passport photo at 300 DPI (UK, EU, India and others).
• 300 × 300 and 400 × 400: avatars, thumbnails and most social profile pictures.
• 1080 × 1080: square social post; 1080 × 1350 for a 4:5 portrait post.
• 1280 × 720: YouTube thumbnail; 1920 × 1080: Full HD screens and wallpapers.
• 1200 × 630: link preview image shown when a page is shared on social networks.
