The resizer uses your browser's HTML5 Canvas API to redraw your image at the new dimensions. Everything runs locally — your images are never uploaded to any server.
Upscaling (making images larger) may reduce apparent sharpness since new pixels must be interpolated. Downscaling (making images smaller) generally preserves quality well. For best results, start with the highest resolution source image you have.
The resizer supports JPG/JPEG, PNG, and WebP images for both input and output. You can choose your preferred output format in the settings.
Yes! The aspect ratio lock is enabled by default. When locked, changing the width automatically adjusts the height (and vice versa) to maintain the original proportions.
We include presets for popular social media platforms (Instagram, Facebook, Twitter/X, LinkedIn, YouTube, Pinterest, TikTok), common resolutions (HD, Full HD, 4K), print sizes (A4, Letter, 4x6), and document sizes (passport photos, app icons).
The maximum output size is limited by your browser's canvas implementation, typically around 16,384 x 16,384 pixels. For practical purposes, this covers all common use cases including 4K and large print formats.
