Your files stay on your Mac.
FictionBook files wrap ebook content in XML — chapters, sections, inline formatting tags, and embedded metadata. Converting to plain text removes all markup and exports only the readable prose. Conversion runs locally; files never leave your Mac.
Drag one or more .fb2 files — or an entire folder — into Convertessa. Batch conversion processes every file in a single pass.
Choose Plain Text from the output list. Convertessa strips all FB2 XML tags and metadata, leaving clean readable prose in each .txt file.
Click Convert. Your .txt files appear alongside the originals. Nothing is uploaded — the entire conversion runs on your Mac, offline.
Images, audio, video, documents, archives and eBooks — all converted natively, right on your Mac.
Pick a format you have — see everything Convertessa can turn it into.
Convert hundreds of files at once with per-type group defaults and individual overrides.
First-class support for HEIC, AVIF and WebP — encode and decode, both ways. Read JPEG XL and a dozen more modern formats too.
Drop files anywhere on the window. Native, instant, and exactly what you’d expect on a Mac.
Dial in compression, resolution and bitrate. Keep originals pristine or shrink for sharing.
Never overwrite a file by accident. Convertessa appends safe suffixes automatically.
Every job is logged locally. Re-run a previous conversion or revisit recent outputs in a click.
Bundle your converted files straight into a single ZIP, TAR or 7z — packaged and ready to share the moment a job finishes.
Right-click any file in Finder and choose Convert. A Quick Action handles it on the spot — no need to open the app first.
Shrink Convertessa to a tidy mini window that tucks into a corner — just a drop zone and a format picker for quick, one-off conversions.
No cloud. No account. No upload. Every conversion happens entirely on-device, using the power already in your Mac. What you convert is nobody’s business but yours.
Script conversions, wire them into your build, or batch a folder from the terminal. The same engine, no GUI required.

New formats, new features, and fixes — every release, on the record.
They are stripped. Plain text carries no markup, so inline formatting and structural tags from the FB2 XML are removed and only the character content remains.
No. Plain text cannot contain images, so any covers or illustrations embedded in the FB2 file are discarded during conversion.
No. Convertessa strips FB2 metadata tags so the .txt file contains only the body prose, not the document description block.
