PDFify is a small macOS tool for combining pages from different sources to one PDF and applying text recognition if required.
Text Recognition - OCR with PDFify
Text recognition is automatically applied to images or PDF files that do not contain text information. If text information already exists, the OCR button can be used to force recognition of the entire document. OCR can be applied several times to the same document with different settings to get optimal results.
Two implementations are available for text recognition:
Tesseract
Tesseract is a very mature open source solution that is supported by large companies. Version 4, used in PDFify, is state of the art and fast enough for ease of use.
Over 100 languages are available with Tesseract. Separate data sets optimized for speed and quality are in place for each language. In the setting dialog you can choose between fast and best. We recommend to only select a limited number of languages.
Apple Vision
Apple Vision OCR is a in macOS and iOS integrated solution that supports English, French, Italian, German, Spanish, Portuguese and Chinese; prior to macOS Big Sur only English. 
To improve the results, it is possible to optionally use the most accurate recognition mode as well as apply language correction.
Add Pages
You have two options for getting started with PDFify:
- Start with an blank document
- Open an existing PDF with PDFify. Apply OCR manually if necessary.
You can add new pages by dragging and dropping the content onto the PDFify window. You can also drag your document onto the dock icon to open the app directly.
Furthermore, you can also add content
- by copying and pasting files, PDFs, images, screenshots and more, and
- choosing
Add Pagesfrom the toolbar or the main menu entries belowPages.
Note
You can always undo to return to the previous state.
The contents are imported at the end of documents in the sorting familiar from the Apple Finder.
If you want the new pages to be placed on top of the document, you must check the corresponding box in the settings.
Note
You can also adjust the order of the pages manually by moving them with the left mouse button.
You can easily import content into PDFify from a file, clipboard or screenshot using the toolbar or Pages from the main menu. You can also use your iPhone, iPad or scanner to insert pages into PDFify.
Add from iPhone / iPad (Continuity Camera)
If you have an iPhone or iPad “within reach”, the options to take a photo, scan documents or add a drawing via the mobile device appear in the menu. PDFify delivers an optimal result by reducing the white border that otherwise appears with this option. The mobile device becomes a convenient document scanner.
You can findmore details at Apple.
Add from Desktop Scanners
PDFify provides you a comfortable scanner dialog. It shows a list of all available devices on the left. After selecting a scanner the macOS scan interface will show up with the usual options. All scanned pages are attached to the current document and are applied to OCR. Press Done to leave the dialog.
Note
The following have proven to be good default settings:
Type: Color or gray Resolution: 300dpi
Caution
Some scanners have problems with the “black and white mode”. This problem can be solved by setting the option “Show file type chooser” in the PDFify settings. This will create a temporary file when scanning. Unfortunately, this is a bug in the operating system that makes this workaround necessary.
Add from ScanSnap
Particularly good results can be achieved with a document scanner such as ScanSnap from the manufacturer FUJITSU.
The following video shows how to integrate the Receipts app directly into ScanSnap Home. For PDFify the steps are the same :

Drag & drop from mails
You can drag and drop selected emails to PDFify - either directly onto the window or the dock icon. A PDF with A4 pages is created and the print dialog is conveniently skipped completely. Most email applications, including Apple Mail, MailMate, AirMail and Postbox are supported. Spark is not supported; there you have to make a workaround via the print dialog.
Drag & drop of webpages
Also web pages are automatically converted to paged PDF files. Drag the URL from your favorite browser on a PDFify window. URLs that are in the clipboard can also be easily pasted and the website is attached to the document.
Work with PDF
Apply OCR
Text recognition is automatically applied to images or PDF files that do not contain any text information. If text information is already present, the OCR button can be used to initiate recognition of the entire document.
If you open PDF files or add PDF pages to a document, it may already contain text information that you may want to keep. You therefore decide whether these pages should be OCR’d or not.
Technical Details
Why is text recognition not always started automatically? If a PDF file already contains text information, this can be changed by applying OCR to the text again. If you then copy this, for example, and paste it elsewhere, you will notice that the characters do not match their representation. As the algorithm cannot identify this 100%, the decision is up to you.
PDF/A Support
Many PDFify users keep electronic documents that they need to archive for the long term. PDF/A - Portable Document Format Archivable - enables standardized long-term archiving of documents. As of macOS 11, PDFify offers to save the document as PDF/A-2u by default in the settings.
Data loss
The saving options mentioned may remove information (e.g. embedded information such as links, graphics, audio and video files and optional encryption) from the PDF in order to meet the specifications. It is therefore recommended to check the result, as this could lead to data and quality losses.
Squeeze
The size of the PDF file can be optimized by changing the image quality. The following default settings are available:
- Original: The original data is retained. No further changes to the data, although it is possible that the original data already contains compressions, which may also result in good values.
- Light compression: 300 dpi, 80% quality.
- Medium compression: 144 dpi, 75% quality.
- Strong compression: 72 dpi, 50% quality.
The current file size is now displayed in the center of the lower status bar.
After compression has been applied, a message is displayed showing how much the file size has changed from the previous value.
In the preferences you can set the optimization to be used for newly added pages.aster display of PDFs on the web
Furthermore, you can now also select the linearized PDF, which is optimized for fast display on the Internet. The first page is then already displayed during the download, while the following pages are still being loaded.
Faster display of PDF on the web
Furthermore, you can now also select the linearized PDF, which is optimized for fast display on the Internet. The first page is then already displayed during the download, while the following pages are still being loaded.
Standardized maximum page size
PDFify allows you to limit the maximum page size so that you do not end up with unsightly huge pages. By default, the page size is set to DIN A4 with the update. In the settings, you can adjust the value to the original size or US letter.
Sequence during import
Sometimes the individual pages of a document are available as separate image files. These are imported in the sort order familiar from the Apple Finder. This allows individual scans of pages to be quickly merged into one PDF document.
Undo / Redo
All operations done can also be undone or redone. Go to the main menu and choose Undo or Redo from the Edit menu. You can also use the keyboard shortcuts CMD + Z or CMD + SHIFT + Z as in any other good Mac application.
Delete and Rotate Pages
Directly in the PDF, the actions for deleting or rotating the page currently under the cursor can be selected in the context menu. After a short delay, a corresponding option appears in the thumbnail view.
Info
The rotation of a page has, in contrast to changes at the document, influence on the text recognition. Thus after a rotation an already accomplished text recognition is also rotated. However, if a new text recognition is performed, the current rotation is taken into account and text from top to bottom is recognized again.
Work faster with batch processing
This feature allows you to turn multiple documents “in a batch” at once into searchable PDF, PDF/A or to shrink their file size. The “Create Searchable PDF” and “Convert in PDF/A” features can be applied to images (PNG, JPG, etc.) in addition to PDF, but “squeeze” can only be applied to PDF.
You select several documents and apply a so-called “quick action”. The respective quick action creates a new file with the extension “.searchable.pdf”, “.pdf/a.pdf” or “.min.pdf” at the same location for each document. If you prefer to overwrite the original file, a corresponding check mark must be set under “Actions” after the “Quick Actions” settings described below.
You can execute these “Quick Actions” directly in the Finder:
- “Create Searchable PDF”
- “Convert in PDF/A”
- “Squeeze PDF”
Before the first “batch processing” the “Quick Actions” must be adjusted via the right mouse button…
… and selected accordingly.
The added “Quick Actions” are now displayed for selection in the Quick Actions as well as in the view below the PDF and can be applied in one step compared to the more cumbersome processing in the UI. The settings from the main app for Squeeze and OCR are carried over.
In the column view in the Finder:
Of course, the Quick Actions also work for individual documents.
