Case Change

You are reviewing a contract and need to circle a clause. You are marking up a student assignment and want to sketch a correction in the margin. You have a blueprint or technical diagram that needs annotations drawn directly on the page. In every case, the question is the same: how do you draw on a PDF without printing it, without buying Adobe Acrobat, and without spending ten minutes figuring out a complicated tool?

ASCII art is everywhere in 2026 — game chat, developer README files, Discord servers, anime communities, social media bios, and terminal screens. And the demand for tools that generate it has never been higher. Whether you want to turn text into bold ASCII letters, convert a photo of your cat into character art, create Valorant chat drops, or generate cute anime girl ASCII portraits, there is a dedicated tool for every use case.

BMP files are enormous. A single uncompressed bitmap image can be 10, 20, even 50 times larger than the equivalent JPG — with no visible quality advantage for most use cases. Sending a BMP by email, uploading it to a website, or sharing it on social media is slow, impractical, and in many cases simply impossible due to file size limits.

This guide covers the full JPG vs JPEG story, when and why you might need to change between them, and how to convert your JPEG to other formats like WebP, BMP, TIFF, and SVG using Transfonic's free Image Conversion tool — no software, no signup required.
