Frequently asked questions
How do I resize an image to 20 KB and specific dimensions (e.g. 3.5cm x 4.5cm)?
Set the dimensions, enable the file size target, and enter 20 KB. The tool keeps the dimensions fixed and tells you if the smallest output still exceeds the target.
What DPI should I use for government and passport photos?
Use the dimensions and DPI specified on your form. For example, 3.5 × 4.5 cm at 300 DPI comes to about 413 × 531 pixels.
Are the tools free?
Yes. You can use every tool without an account, payment, or daily quota. The website adds no watermark.
Where are my files processed?
Your browser processes files and text on your device. The website does not upload your inputs.
What file sizes can I use?
Available browser memory and file complexity determine what will work. Image tools process up to 20 files per batch. Try smaller batches for large images.
