Frequently Asked Questions
Quick answers about file limits, supported formats, and common upload situations.
Can I compress an image to exactly 100KB or 200KB?
Yes. You can set targets like 100KB and 200KB directly. The final result depends on the original file, but the tool is built for this kind of request.
Can I compress PDF files to a specific KB size?
Yes. PDF compression can be aimed at a specific size for upload limits, email attachments, and portal requirements.
Which file types does ExactSizer support?
ExactSizer supports JPG, HEIC, PNG, WebP, GIF, and PDF files.
Will my files stay private?
Yes. Files stay on your device during compression, which makes ExactSizer a good fit for sensitive documents and images.
What if my file cannot hit the exact target?
Some files have less room to shrink than others. In those cases, ExactSizer aims for the closest practical result while keeping the file usable.
Can I use ExactSizer for form, visa, or job application uploads?
Yes. ExactSizer is especially useful when a portal asks for a strict file-size limit such as 100KB, 200KB, or 500KB.
Do I need to install anything to use ExactSizer?
No. You can open the page, choose your file, set your target size, and download the compressed result in the same session.
What does 'file size greater than 100KB' mean?
It means the file is currently too small and must be larger than 100KB. However, most users see the opposite error: 'file exceeds maximum size.' ExactSizer helps you shrink files to fit those maximum limits.
