FAQ
How do I resize a PNG without losing quality?
Keep the aspect ratio locked and resize by pixels rather than upscaling. Because the tool processes your PNG locally in the browser, there's no re-compression from an upload — the main cause of quality loss.
Is this image resizer free?
Yes, completely free. No signup, no watermark, no usage limits.
Can I resize images without uploading them?
Yes. Files are processed entirely in your browser and never leave your device.
What size should I resize images to for Instagram?
1080 × 1350 for portrait, 1080 × 1080 for square, and 1080 × 566 for landscape. Instagram compresses everything, so keep the longer side at 1080 px.
How do I resize an image to 1 MB?
Enter your target pixel dimensions, then choose the JPG or WebP quality level that brings the file under 1 MB. Lower quality = smaller file; the preview lets you check sharpness before downloading.
What file formats are supported?
PNG, JPG/JPEG and WebP. You can convert between them while resizing.
