How to Resize Images Without Losing Quality

Use our free image resizer to scale images down by percentage or exact pixel dimensions while keeping them sharp. The key to preserving quality: resize downward (not up), use PNG for graphics, and pick the highest quality setting your file size budget allows.

Why Resizing Can Reduce Quality

Every time you resize a JPG, the image gets re-encoded with lossy compression. Pixels are interpolated, edges soften, and compression artifacts appear. The more you resize and re-save, the worse it gets. PNG files avoid this because PNG is lossless, but they produce larger files.

Best Practices for Sharp Results

• Scale down, not up. Making an image smaller discards pixels cleanly. Making it larger forces the software to invent new pixels, which always looks blurry.
• Start from the original. Never resize an already-resized copy. Go back to the full-resolution source.
• Use PNG or WebP for quality. If file size is not a concern, output as PNG for zero compression loss. For web use, WebP gives excellent quality at smaller file sizes than JPG.
• Keep aspect ratio locked. Stretching images to a different ratio distorts them visibly.

Which Format to Choose

For photos you plan to share online, JPG at 85-92% quality is the sweet spot between size and sharpness. For screenshots, logos, or anything with text, PNG preserves every pixel. WebP works well for both cases and is supported by all modern browsers. Check our PNG vs JPG comparison for a deeper look.

How to Resize Step by Step

Open the Image Resizer, upload your image, and choose a method: percentage (75%, 50%, 25%) or custom pixel dimensions. Lock the aspect ratio, pick your output format, set quality to "Best," and download. The entire process runs in your browser so nothing gets uploaded to a server.
