A TinyPNG alternative for Mac with no upload and no batch cap
By Himanshu Ranjan · Updated 8 November 2026
If you use TinyPNG to shrink images for the web, FileDial does the same jobs on your Mac: compress, convert to WebP, AVIF, JPG or PNG, and hit size targets, on any number of files at once, with nothing uploaded. It is $20 once after a 1-day trial. ImageOptim is a strong free choice if you only need compression.
Why people look for a TinyPNG (Tinify) alternative
- The free web tool takes up to 20 images at a time, 5 MB each. A shoot of 400 product photos means 20 rounds of upload and download.
- Files are uploaded and kept for up to 48 hours, per TinyPNG's own page. That is fine for public web assets, less so for unreleased product shots or client work under NDA.
- Free conversion is limited to three images, and larger files need Web Pro (75 MB) or Web Ultra (150 MB), which are annual subscriptions.
- It needs an internet connection; on a slow link the upload often takes longer than the compression.

What FileDial does not replace:
- JPEG XL: TinyPNG compresses and converts to JPEG XL; FileDial has no JPEG XL tool.
- Developer API, WordPress plugin and CDN: TinyPNG plugs into build pipelines and websites. FileDial is a desktop app for files in Finder.
- Any OS: TinyPNG runs in a browser on Windows, Linux or a phone. FileDial needs a Mac with macOS 14 and Apple silicon.
Details about TinyPNG (Tinify) come from its own website, checked 2026-11-09. FileDial tool names match the app exactly.
The best TinyPNG (Tinify) alternatives for Mac
1. FileDial
FileDial is our app. Select images in Finder, hold the right Option key and choose Compress › Compress, or a size target such as Compress › Compress under 200 KB or Compress › Compress to size… Conversions to WebP and AVIF are one step each, and Resize › Resize to 2048 px handles oversized camera files first. A batch of 300 photos converted in 5 seconds on a MacBook.
- No per-batch or per-file size cap
- Size targets, not just a quality guess
- Nothing uploaded, works with Wi-Fi off
- Not free after the 1-day trial
- Needs macOS 14 or later on an Apple silicon Mac (M1 or newer)
- Mac only, no web, Windows or phone version
- No API or WordPress plugin
2. ImageOptim
ImageOptim is a free, open source Mac app that runs encoders such as MozJPEG, pngquant, Zopfli and SVGO. Lossless by default, with an optional lossy mode in Preferences. It is the closest free match for TinyPNG's core job, minus WebP and AVIF.
- Free and open source
- Drop whole folders on it
- Strips private EXIF such as GPS
- JPEG, PNG, GIF and SVG only
- No conversion or resizing
3. Squoosh
Squoosh runs entirely in your browser; its site says images never leave your device. It shows the original and the result side by side while you adjust quality, which is great for a single hero image and slow for a folder.
- Free, local processing in the browser
- Many encoders including AVIF, WebP and JPEG XL
- Visual before and after
- One image at a time
- Google Analytics records before and after sizes
4. Preview (built into macOS)
Preview can export JPEG with a quality slider and reduce resolution with Tools › Adjust Size, including for several images selected in the sidebar. It does not write WebP or AVIF from the standard export menu.
- Free and installed
- Batch resize from the sidebar
- No WebP or AVIF export in the standard menu
- No size targets
Is TinyPNG still worth using?
Yes, for some people. TinyPNG's compression is well regarded, the free tier is generous for a few images a week, and the API is a sensible choice for a website that compresses uploads automatically. If that is you, keep using it.
It stops fitting when you work in bulk, when files are confidential, or when you are offline. A designer exporting 60 screens, a shop owner with 400 product photos or anyone on a train will hit the 20-image batch, the 5 MB cap or the connection first.
Replace a TinyPNG session in FileDial
Here is the usual TinyPNG routine, upload, wait, download the ZIP, done as one step on your Mac.
- Select every image in the folder in Finder.
- Hold the right Option key and move to Compress.
- Release on Compress for smaller copies that look the same, or Convert › Convert to WebP if your site serves WebP.
- Read the result card for the total size before and after. New files sit beside the originals, so nothing is overwritten.
Size targets instead of guesswork
TinyPNG decides how far to compress. That is convenient, but upload forms, marketplaces and email care about a number. FileDial's Compress category includes Compress under 2 MB, Compress under 1 MB, Compress under 500 KB and Compress under 200 KB, plus Compress to size… for any other limit. If you need exact dimensions too, Resize › Open Graph image (1200×630) and Resize › YouTube thumbnail (1280×720) export ready-made JPGs.
When to pick a free tool instead
If you compress a handful of PNGs a week and never need WebP or AVIF, ImageOptim is free, open source and runs on your Mac, so it removes TinyPNG's upload and batch limits at no cost. FileDial is worth the $20 when you also convert formats, need size targets, or want the same app for PDFs, video and audio.
Questions
Is there a TinyPNG app for Mac?
TinyPNG does not list a Mac app on its site. It offers the web compressor, a developer API with client libraries and a WordPress plugin. If you want TinyPNG-style compression in a Mac app, ImageOptim is free and FileDial covers compression plus WebP, AVIF, JPG and PNG conversion, all without uploading.
Can I use TinyPNG offline?
No. TinyPNG works by uploading your images to its servers, and its page says it keeps them for up to 48 hours before deleting them. For offline compression on a Mac, ImageOptim and FileDial run locally, and Squoosh processes images inside your browser once the page has loaded.
What are TinyPNG's free limits?
On 9 November 2026 its homepage listed up to 20 images at once with a maximum of 5 MB each, and free conversion limited to three images. Web Pro raises the file limit to 75 MB and Web Ultra to 150 MB. The developer API gives 500 free compressions a month.
Does FileDial compress PNG as well as TinyPNG?
We have not run a lab comparison, so we will not claim a percentage. FileDial's Compress › Compress makes a smaller copy that looks the same, and the result card shows the exact size before and after so you can judge each batch yourself. If a file must hit a number, use a size target such as Compress under 500 KB.
Is TinyPNG free for commercial use?
TinyPNG's pages describe free web use and paid Web Pro and Web Ultra plans; they do not restrict the free tier to personal use on the pages we checked. For heavy or automated use, the API charges per compression after the free 500 a month. Read its terms if you need a definite answer for your business.
