Frequently Asked Questions
How do I resize an image to specific pixels free online?
Upload your image, select the Pixels tab, enter your target width and height and click Resize Images — no sign-up, no watermark. Lock the aspect ratio to prevent distortion. Works for any size: 1920×1080, 1080×1080, 800×600 or any custom dimension.
How do I resize images for Instagram without cropping?
Use the Presets tab and select 1080×1080 for square posts, 1080×1920 for Stories or 1080×1350 for portrait posts. The aspect ratio lock ensures your image is scaled proportionally with no cropping or distortion — free, no watermark and no sign-up required.
How do I resize an image for email without losing quality?
Upload your image, use the Percentage tab and resize to 50% — this halves the file size while keeping proportions correct. Or use the Pixels tab and set a maximum width of 800px, which is ideal for email. Download as JPG for the smallest file size that still looks sharp.
Can I resize HEIC photos from my iPhone?
Yes — upload your HEIC or HEIF files directly. They are decoded in your browser and resized to your chosen dimensions. Perfect for resizing iPhone photos before sharing on Windows, Android or any platform where HEIC is not natively supported.
What does locking the aspect ratio mean?
Aspect ratio is the proportional relationship between an image's width and height. Locking it means when you change the width, the height adjusts automatically — keeping your image proportional and preventing it from appearing stretched or squashed.
Can I resize and compress at the same time?
The resizer maintains high quality output by default. For additional file size reduction after resizing, use our free image compressor which can reduce file sizes by up to 90% while keeping the same pixel dimensions.
Can I batch resize images free online?
Yes — upload up to 20 images at once and they all resize to the same dimensions. Download them individually or all at once as a ZIP file. Free, no watermarks, no sign-up. You can also crop images to a specific ratio using our free cropper tool.
Is this image resizer completely free with no watermark?
Yes — completely free with no usage limits, no watermarks and no account required. All tools on FreeConverto including the image converter, compressor and cropper are free forever.
