MOBI to PSD Converter
FileFlip converts MOBI to PSD entirely inside your browser, using MuPDF and ImageMagick compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert a MOBI file to PSD?#
- Drop your MOBI file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to PSD and the conversion starts on its own. FileFlip downloads 24.1 MB of WebAssembly the first time and nothing after that, then runs MuPDF and ImageMagick on your own machine.
- Save the PSD file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting MOBI to PSD lose quality?#
Yes, in the sense that text stops being text. Each MOBI page is rendered to pixels and handed to PSD, so the result looks right and can no longer be selected, searched, or reflowed.
Is it safe to convert MOBI files online?#
Yes, because nothing is uploaded. FileFlip converts MOBI files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What MOBI to PSD actually does to the file#
Converting MOBI to PSD runs on MuPDF and ImageMagick, downloads 24.1 MB of WebAssembly the first time and nothing after that, renders each page to pixels, keeps page layout, and drops selectable text and transparency.
| Engine | MuPDF and ImageMagick |
|---|---|
| Conversion path | 2 steps: MOBI → PNG → PSD |
| Downloaded to your browser | 24.1 MB, once, then cached by your browser |
| Quality | Text becomes pixels |
| You get back | One image per page, zipped when the source has several |
| Where it runs | In a background worker, so the page stays responsive |
What survives the conversion
| What is in the file | This conversion | Why |
|---|---|---|
| Selectable text | Dropped | The target format has nowhere to put it. |
| Page layout | Kept | Carried through into the converted file. |
| Transparency | Dropped | The target format has nowhere to put it. |
Worth knowing before you start:
- pages render at twice their point size in opaque RGB, roughly 144 DPI, with no transparency
- reflowable input is laid out on a fixed 595x842pt page at 11pt before anything else happens
What is a MOBI file?#
A MOBI file holds an ebook in Mobipocket's format, a text document compressed and stored inside a Palm Database (PDB) container that Amazon adopted for the original Kindle.
There is little reason to create a new MOBI file today; it matters only for reading an ebook already saved in the format.
Convert MOBI to EPUB or PDF because Amazon no longer accepts MOBI directly and current Kindle software expects KFX or EPUB instead.
What is a PSD file?#
A PSD file is Adobe Photoshop's native document format, keeping an image as a stack of independently editable layers, masks, adjustment layers and text objects instead of merging them into a single picture.
Keep a design as PSD while it's still being edited, so layers, masks and adjustment layers stay available for later changes.
Convert PSD to JPEG or PNG once a design is finished and needs to be viewed on the web or by someone without Photoshop, since flattening is what makes it viewable everywhere.
MOBI to PSD questions people ask#
What is a MOBI file?
A MOBI file is an ebook in the format Mobipocket built on top of the Palm Database (PDB) container, the same file structure Palm OS devices used for their own databases. Amazon acquired Mobipocket in 2005 and used the format for the first decade of Kindle devices.
Why won't my MOBI file work on my Kindle anymore?
Amazon announced in April 2022 that it would stop accepting MOBI files through Send to Kindle and Kindle Direct Publishing by the end of that year, converting uploads to KFX or the EPUB-derived AZW3 format instead. A MOBI file made before that change often still opens on an older Kindle, but current Kindle software and newer devices expect the file already converted.
What replaced the MOBI format?
KFX, Amazon's current Kindle format, replaced MOBI, along with AZW3 (Kindle Format 8) which Amazon introduced back in 2011. Both handle layout and typography that the older MOBI format cannot, and Amazon now converts incoming EPUB files to KFX rather than accepting MOBI as an input.
Can I remove DRM from a MOBI file to convert it?
No converter can remove DRM from a MOBI file. Mobipocket and Amazon both used encryption schemes tied to a device or account registration, and a protected MOBI file will fail to convert rather than produce readable output.
