Tips for Resizing Images
Always Start with High Resolution
For the best results, upload the highest resolution version of your image. Scaling down preserves quality, but scaling up can cause blurriness.
Use Platform Presets
Each social media platform has specific recommended dimensions. Using the correct size ensures your images display without cropping or distortion.
Lock the Aspect Ratio
When using custom dimensions, keep the aspect ratio locked to prevent your image from looking stretched or squished. Unlock only if you intentionally want to change proportions.
Choose the Right Format
Use PNG for images with transparency or text. JPEG for photos (smaller file size). WebP for the best compression-to-quality ratio on modern browsers.

Frequently Asked Questions
Is this image resizer really free?
Yes, the Image Resizer is 100% free with unlimited use. There is no sign-up required and no daily limits. All processing happens directly in your browser.
Are my images uploaded to a server?
No. All image processing happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device, ensuring complete privacy and security.
What image formats are supported?
You can upload PNG, JPG, WebP, GIF, BMP, and SVG images up to 20MB. For export, you can download your resized image as PNG (lossless), JPEG (adjustable quality), or WebP (best compression).
Will resizing make my image blurry?
Scaling an image down preserves quality well. Scaling up beyond the original dimensions can cause some loss of sharpness, which is a natural limitation of raster images. For best results, start with the highest resolution source.
What social media sizes are available?
We include 14+ presets covering Instagram (Post, Story, Profile), Facebook (Cover, Post, Profile), X/Twitter (Header, Post), LinkedIn (Banner, Post), YouTube (Thumbnail, Channel Art), Pinterest (Pin), and TikTok (Video).
Does locking the aspect ratio affect quality?
No. Locking the aspect ratio simply maintains the original width-to-height proportion when you change one dimension. It prevents distortion and does not affect image quality.
