Frequently Asked Questions
How do I resize an image without losing quality?
Use the quality slider set to 90-100% when resizing. For best results, only downscale (make smaller) rather than upscale. Filator uses high-quality image smoothing algorithms to minimize quality loss during resizing.
What is the best image size for Instagram?
For Instagram posts, use 1080×1080 pixels (square), 1080×1350 (portrait), or 1080×566 (landscape). For Stories and Reels, use 1080×1920 pixels. Profile pictures should be 320×320 pixels.
Can I resize multiple images at once?
Yes, Filator supports batch processing with no limits. Upload multiple images, set your desired dimensions, and resize them all with one click. Download individually or as a ZIP archive.
Is it safe to resize images online?
With Filator, absolutely. All processing happens in your browser—your images are never uploaded to any server. This is different from most online tools that require server uploads and temporary storage.
What image formats are supported?
Filator supports all common image formats including JPEG, PNG, WebP, GIF, and BMP. You can also convert between formats during the resize process (e.g., resize a PNG and export as JPEG).
How do I maintain aspect ratio when resizing?
Click the lock icon between width and height fields to maintain aspect ratio. When locked, changing one dimension automatically adjusts the other to prevent image distortion.
What's the difference between resizing and cropping?
Resizing changes the overall dimensions while keeping all content. Cropping cuts out a portion of the image, removing parts of the picture. Resizing makes your whole image bigger or smaller; cropping removes areas you don't want.
Do I need to create an account?
No. Filator is completely free with no signup, no account creation, and no email required. Just upload and resize—no strings attached.
