Frequently asked questions
How do I convert my files?
Choose or drop your files, adjust the options if you like, then press “Convert” and download the result.
Are my files uploaded to a server?
No. The conversion runs entirely in your browser, so your files never leave your device — safe for private photos and documents.
Is there a file size limit?
There is no fixed limit. Very large files (hundreds of MB) depend on your device's memory and can be slow on phones.
Is it free?
Yes — free and unlimited, with no sign-up and no watermark.
About the formats
PNG
PNG is a lossless image format that supports transparency. It is best for screenshots, logos and graphics with text; photos saved as PNG are much larger than JPG.
