FastCompressor vs TinyPNG: The Honest Comparison (2026)

Quick comparison

TinyPNG pricing verified June 2026 at tinypng.com.

Speed benchmark

We compressed the same batch — 100 JPG files averaging 3.2 MB each — with both tools on a MacBook Air M2, 200 Mbps connection.

At 100 files, the upload/download overhead of TinyPNG alone takes over 5 minutes before any compression even happens. FastCompressor's entire pipeline — including compression — runs in under 15 seconds for most batches of this size.

What TinyPNG does well (and where it genuinely beats FastCompressor)

Being honest matters here. TinyPNG has real strengths:

WordPress plugin. TinyPNG's WordPress plugin automatically compresses images on upload, in the background, without any manual workflow. FastCompressor has no WordPress integration — if you need automatic WordPress compression, TinyPNG's plugin is hard to beat.

Developer API. TinyPNG's API is well-documented, supports Python, Node.js, PHP, Ruby, .NET, and Java, and is used by thousands of production pipelines. FastCompressor has no API. If you need programmatic compression integration, TinyPNG is the right choice.

Where FastCompressor wins

No upload. Ever. Every image you send to TinyPNG is uploaded to Tinify's servers. TinyPNG states files are deleted after processing — there's no reason to doubt that statement. But for client photos under NDA, images with GPS coordinates, medical images, or sensitive business assets, uploading to a third-party server is a meaningful concern. FastCompressor processes everything locally. Your files never leave your device.

No file size limit. TinyPNG's free tier caps files at 5 MB each. A single RAW export from a modern camera, a Lightroom TIFF, or a high-resolution product photo routinely exceeds this. FastCompressor has no per-file limit — handle 200 MB TIFFs or multi-gigabyte videos without restriction.

TIFF compression. TinyPNG does not support TIFF files at any tier. FastCompressor compresses TIFF losslessly using LZW or Deflate, automatically selected based on the file's bit depth. For photographers, print designers, and archivists, this is non-negotiable.

Video compression. TinyPNG is images only. FastCompressor compresses MP4, MOV, and WebM in the same app — no second tool needed.

One-time price vs recurring subscription. TinyPNG Pro is $39/year. FastCompressor Pro is $19 once — no annual renewal, no subscription, no usage meters. Over 3 years, TinyPNG Pro costs $117. FastCompressor Pro costs $19.

Works offline. No internet connection required. Compress images on a plane, in a secure corporate environment, or anywhere else with no connectivity.

Real compression quality comparison

TinyPNG uses lossy compression by default. FastCompressor offers both lossless and lossy modes.

For most web use cases, both tools produce visually identical output. However, FastCompressor wins decisively on speed and workflow efficiency. Because it runs locally on your machine, it saves massive amounts of time—especially when you need to batch process dozens or hundreds of files at once, completely bypassing the slow upload and download cycles of web-based tools.

Who should use TinyPNG

• You compress fewer than 20 images at a time and they're all under 5 MB
• You run a WordPress site and want automatic compression on upload
• Your team needs API integration for an automated pipeline

Who should use FastCompressor

• You compress 20+ files at a time, or work with files over 5 MB
• Your images include client work, GPS data, or sensitive content that shouldn't leave your device
• Your workflow includes TIFF, AVIF, GIF, or video files
• You work on Windows, Mac, or Linux and want a native desktop app
• You want to pay once and never think about it again

Frequently asked questions

Is FastCompressor faster than TinyPNG?
For batches of 20 or more images, yes — significantly. TinyPNG requires uploading files to a server, waiting for processing, and downloading a ZIP file. FastCompressor compresses locally, so the only time is the CPU processing time. For a 100-image batch, FastCompressor typically finishes in 5–15 seconds. TinyPNG requires 5–6 minutes for the same batch.

Does FastCompressor work without TinyPNG's API?
Yes. FastCompressor is a standalone desktop app with no dependency on TinyPNG or any external API. It works fully offline.

Can I switch from TinyPNG to FastCompressor mid-project?
Yes. FastCompressor accepts the same input formats as TinyPNG (JPG, PNG, WebP, AVIF) and produces the same output formats. You can start using it on any new batch without any setup beyond downloading the app.

Does FastCompressor have a WordPress plugin?
No. FastCompressor is a desktop app that compresses files before you upload them. If you need automatic WordPress compression on upload, TinyPNG's plugin or ShortPixel are better options for that specific use case.

Which is cheaper long-term?
TinyPNG Pro costs $39/year. FastCompressor Pro costs $19 once. After the first year, TinyPNG Pro costs $39 more. After 3 years, you've paid $117 for TinyPNG vs $19 for FastCompressor — for tools that cover overlapping but not identical use cases.

Is FastCompressor safe to download?
Yes. FastCompressor is independently tested by Softpedia and listed as 100% clean.
