Resize Image

Resizing changes pixel dimensions (width and height). Compressing reduces file size, often without changing visible dimensions.

Resizing a 4000x3000 photo to 1080x1080 for Instagram changes the pixel count drastically. Compression keeps the same dimensions but makes the file smaller by discarding less-important visual data.

On this page you can do both in one step: pick your dimensions, choose a format, and adjust quality.

Each platform has its own ideal dimensions. Wrong sizes can result in awkward crops or blurry previews.

Instagram posts: 1080x1080 (square) or 1080x1350 (portrait). Stories and Reels: 1080x1920. YouTube thumbnails: 1280x720. Facebook feed: 1200x630.

This tool includes presets for Instagram, TikTok, YouTube, Facebook, X, LinkedIn, Pinterest and more. Pick the one you need and the dimensions are set for you.

Blurriness happens when you enlarge beyond the original pixel dimensions. The tool creates new pixels that were not in the original, which reduces sharpness.

Start with the highest resolution source you have and resize down rather than up. This tool uses Lanczos resampling, a high-quality algorithm, but it cannot create detail that was not there to begin with.

If you need to significantly enlarge an image, try our AI upscaling tool which can add realistic detail.

Yes. Select Fit mode. It scales your entire image to fit within the target dimensions and fills leftover space with a background color (white for JPG, transparent for PNG).

Fill mode does the opposite: it scales to cover the entire frame and crops whatever overflows. If a wide landscape photo goes into a square frame, Fit preserves the whole image and adds padding; Fill crops the edges.

For quick social posts, try a preset with Fit mode to avoid losing any part of your photo.

It depends on your use case:

JPG: safest choice for photos, supported everywhere. PNG: use when you need transparency or lossless quality. WebP: smaller files than JPG at similar quality, works on all modern browsers.

AVIF: smallest files with best quality, but older apps may not support it yet. For social media and web, WebP is usually ideal. For print or guaranteed compatibility, go with JPG.

Print needs more pixels than screens. A good rule is 300 pixels per inch (PPI). Multiply your print size in inches by 300: an 8x10 print needs 2400x3000 pixels, a 4x6 photo needs 1200x1800.

The Print preset tab has these calculations built in. Pick 8x10, 5x7, A4, US Letter, or Poster.

Note that printing uses CMYK color space while screens use RGB. This tool works in RGB, which is fine for most home and online print services.
