Image Resizer

What is an image resizer?

An image resizer changes the dimensions of a photo — its width and height in pixels — so it fits a specific requirement.

You might need a smaller image to upload to a website that has a size limit, an exact square for a profile picture, or precise dimensions for a passport or visa application. Resizing changes how many pixels the image contains, which also affects the file size: fewer pixels usually means a lighter file. This tool does the resizing entirely in your browser, so your photo is never uploaded to a server and the result is ready in seconds.

Resizing is different from compressing. Resizing changes the dimensions (for example, from 4000×3000 down to 800×600), while compressing keeps the dimensions but lowers the file size by reducing quality. If your dimensions are already right but the file is too large, use the image compressor instead.

How to use it

1. Upload a JPG, PNG, or WebP image.
2. Pick a preset, or type a custom width and height in pixels.
3. Keep "aspect ratio" locked to avoid stretching, then click Resize and download.

How to resize an image to 200×200 pixels

A 200×200 pixel square is a common size for small profile pictures, icons, and forum avatars. To create one here:

1. Upload your image.
2. In the width box type 200 and in the height box type 200.
3. If your original photo is not already square, turn off "Keep aspect ratio" so it fits an exact 200×200 box — but note this can squash a rectangular photo. For best results, start with a square crop, then resize.
4. Click Resize, then download your 200×200 image.

The same steps work for any exact size, such as 300×300, 512×512, or 1000×1000 — just type the numbers you need.

How to resize an image for a passport or visa photo

Many passport and visa applications ask for a photo at exact pixel dimensions. This tool includes ready-made presets for the most common ones, so you can avoid measuring manually:

• 35×45 mm photo (used by many countries, including the UK, EU, India, and Pakistan): about 413×531 pixels at 300 DPI.
• US passport / visa (2×2 inches): 600×600 pixels.
• India passport (35×45 mm, commonly accepted online): around 350×450 pixels.

Select the matching preset, click Resize, and download. Official photo rules also cover background colour, head position, and lighting, and they vary by country and authority — so always check the exact specification from the official source before you submit. This tool handles the pixel dimensions; it does not check whether your photo meets the other official requirements.

Common image sizes for social media

Social platforms display images best at certain dimensions. These sizes are widely used, though platforms do update them from time to time, so confirm with the platform if it matters:

• Instagram — square post 1080×1080, portrait post 1080×1350, story/Reel 1080×1920.
• Facebook — shared post image 1200×630, cover photo about 820×312.
• X (Twitter) — in-stream image 1600×900, header 1500×500.
• LinkedIn — post image 1200×627, cover 1584×396.
• YouTube — thumbnail 1280×720.
• Pinterest — standard pin 1000×1500.
• WhatsApp — profile picture around 640×640.

Type any of these into the width and height boxes, or start from the social presets in the tool above.
