A LITTLE KNOW-HOW
Better files start with good choices.
Short, practical guides for the things you do every day.
JPG, PNG or WebP: choose the right image format
Choose a format for photos, screenshots and transparent graphics, then check quality and file size before sharing.
Read the guideCombine images into a PDF that is ready to share
Put pictures in the right order, choose a page size and avoid common readability mistakes when making an image-based PDF.
Read the guideWhat private browser-based file processing means
Understand the difference between local file processing and website traffic, and review your downloads before sharing them.
Read the guideAre these tools really free?
Yes. The tools currently available on asdftools are free to use without creating an account. Each tool lists its supported formats and limits.
Do you upload or keep my files?
No tool uploads your files or text to our server. Processing happens in your browser. Closing or refreshing the page clears the workspace. Website access logs and messages you choose to send through Contact are separate; our privacy notice explains them.
Can I use asdftools on my phone?
Yes, with a recent browser. Large images, long PDFs and ZIP files need more memory, so a desktop may work better. Tool-specific size limits help keep processing manageable.
Are the tools powered by AI?
The tools available today use local, deterministic processing rather than a live AI model. We use AI-assisted development and are exploring optional AI workflow guidance. Future AI features will be clearly labeled before you choose to use them.
Make room for the work that matters.
Let the small tasks be small.
