An offline alternative to Online-Convert.com on Mac
By Himanshu Ranjan · Updated 8 November 2026
Online-Convert.com limits free uploads to 75 MB and sells credits in euros for bigger jobs. On a Mac, FileDial covers its main converters, compressors, OCR and checksums locally, with no size cap and no upload, for $20 once. For occasional free conversions, Preview, HandBrake and LibreOffice already work offline.
Why people look for an Online-Convert.com alternative
- The free upload limit is 75 MB, below many phone videos and scanned PDFs.
- Credits are priced in euros and pay-as-you-go credits expire after a year; subscription credits do not roll over.
- Free tasks are queued and capped at 10 minutes of processing, per the pricing page.
- The browser extensions still send files to a server; they are a shortcut to the website, not local conversion.

The best Online-Convert.com alternatives for Mac
1. FileDial
FileDial is our app. It replaces the parts of Online-Convert.com most people use: format converters such as Convert › Convert to MP4 and Convert › Convert to PNG, compressors such as Compress › Compress PDF, OCR through Convert › PDF to Word, and Batch › Checksums (SHA-256) for hashes. Everything runs on the Mac with no 75 MB ceiling.

- Results saved beside originals, with Undo
- Not free after the 1-day trial
- Needs macOS 14 or later on an Apple silicon Mac (M1 or newer)

2. LibreOffice
LibreOffice is a free office suite for macOS 11 or newer on Intel or Apple silicon. Opening a document and exporting it in another format, such as a Word file to PDF, is a common free way to convert documents offline.
- Free
- Opens and saves many document formats
- Exports PDF
- One document at a time through the interface
- Large install for occasional use
3. HandBrake
HandBrake is an open-source video transcoder for Mac, Windows and Linux that converts most common video files to MP4, MKV or WebM, with crop, resize and subtitle options. It handles video only, cannot join clips and does not work with DRM-protected files.
- Free on Mac, Windows and Linux
- Deep quality controls and presets
- Good for large video batches
- Video only
- Many settings to learn
4. Preview and Finder Quick Actions (built into macOS)
Preview exports images to HEIC, JPEG, JPEG-2000, OpenEXR, PDF, PNG and TIFF, and can convert several at once from one window. In Finder, the Convert Image and Create PDF Quick Actions work on selected files without opening an app.

- Free
- Images and PDFs only
- Few options
What Online-Convert.com covers
Online-Convert.com is one of the older all-purpose converters, made by QaamGo Media GmbH in Germany. Its homepage lists converters for archives, audio, CAD, devices, documents, e-books, images, software, video and webservices, plus a hash generator, website screenshots, compressors for PDF, JPG, PNG and MP4, and OCR.
Its FAQ says the free upload limit is 75 MB and that the company does not keep a copy of your file, which you can delete from the server right after conversion. Premium is credit based and priced in euros.
Checking a download with a checksum, offline
The hash generator is a niche but loved part of Online-Convert. There is no need to upload a large installer just to read its SHA-256. FileDial does it on the Mac.
- Select the file, or many files, in Finder.
- Hold the right Option key and open the Batch category.
- Release on Checksums (SHA-256), or Checksums (MD5), (SHA-1) or (SHA-512) to match what the publisher lists.
- A text file of checksums is written beside the files, ready to compare with the published value.
Credits, queues and size limits
Online-Convert's pricing page lists Pay As You Go at €13.00 for 480 credits, which roll over monthly but expire after a year, and subscriptions of €22.42 for 2,800 credits or €68.00 for 10,000, which do not roll over. Free tasks are queued, limited in size, and capped at 10 minutes of processing.
FileDial replaces that with a 1-day trial of every tool and then $20 once for 2 Macs. Speed depends on your Mac rather than a queue: a 42 MB PDF compressed in about 2 seconds on a MacBook.
Free tools already on your Mac
macOS can compute a SHA-256 in Terminal with the shasum command, Preview converts images and exports PDFs, and LibreOffice converts office documents. HandBrake covers video. Together they replace a lot of Online-Convert's free use. FileDial is for people who want all of it in one place, in batches, from Finder.
Keep Online-Convert bookmarked for the conversions no Mac app handles well, such as CAD drawings or Kindle e-books, and for the times you are on someone else's computer. For the daily jobs, a phone video to MP4, a PDF that is too big to email, a folder of photos to PNG, a local tool is faster to reach and never asks you to wait for an upload.
Questions
What is Online-Convert's free file size limit?
Its FAQ says the limit to upload and convert a file for free is 75 megabytes, and the pricing page also caps free tasks at 10 minutes of processing in a queue. Premium raises the file limit to 64 GB. FileDial has no upload limit, because files are converted on the Mac rather than sent anywhere.
Does Online-Convert keep my files?
Its FAQ states that it does not keep a copy of your file and that you can delete it from the server immediately after conversion. Files still travel to its servers to be converted. With FileDial the conversion happens on your Mac, so no copy is made outside it.
Do the Online-Convert browser extensions work offline?
The extensions for Chrome, Firefox and Edge are a quicker way into the Online-Convert service, which converts on its servers, so they need a connection. For offline conversion on a Mac, use a desktop app such as FileDial, or free tools like Preview, HandBrake and LibreOffice.
Can FileDial convert CAD or Kindle files?
No. FileDial does not list CAD conversion or Kindle formats such as MOBI and AZW3. It does make EPUB from documents and PDFs with Convert › Convert to EPUB and Convert › PDF to EPUB. For CAD or Kindle conversions, Online-Convert or a dedicated tool is the better choice.
