Frequently Asked Questions
What does "Batch" mean here?
"Batch" means you can process multiple files at once. Drop several images, PDFs, or documents, and convert them all in one go—no need to upload files one at a time.
Are there limits or paywalls?
No paywalls or hidden fees. Fair-use limits are shown before you start (like file size caps or processing time). Most tools have no practical limits for everyday use.
Will quality drop when converting or compressing?
For compression, you choose the quality level—higher compression = smaller files but some quality loss. For format conversion (like PNG to WebP), quality is preserved when using lossless settings. We're honest about trade-offs.
Can I use this on mobile or install it as an app?
Yes! All tools work on mobile browsers. You can also install Microtools as a PWA (Progressive Web App) on your phone or desktop—look for the "Install" button or "Add to Home Screen" option in your browser.
What file formats are supported?
Images: PNG, JPG, JPEG, WebP, BMP, GIF, SVG
Documents: PDF, DOCX, DOC, XLSX, XLS, CSV
