You can open and annotate your PDFs without uploading everything to a server or creating an account.</p> <p>I’m still actively improving it, and this is just the beginning.</p> <p>Would love to hear what you think — especially if you work with a lot of PDFs or have ideas for features that would make it more useful.</p> <p><strong>BlazePDF:</strong> <a href="https://blazepdf.app/" rel="noopener noreferrer">blazepdf.app</a></p> <p>Thanks for checking it out! 🔥</p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2Fr86zurrfiv1fo1694kh3.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2Fr86zurrfiv1fo1694kh3.png" alt=" " width="800" height="450"></a></p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2Fohr8pklm2rb2ajo2rxhl.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2Fohr8pklm2rb2ajo2rxhl.png" alt=" " width="800" height="450"></a></p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2Fw2asqmolyrcd5g0pomqr.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.us-east-2.amazonaws.com%2Fuploads%2Farticles%2Fw2asqmolyrcd5g0pomqr.png" alt=" " width="800" height="450"></a></p> showdev software tools
