Best TinyPNG Alternatives in 2026 — Free Tools That Do More
If you have outgrown TinyPNG's 20-file free limit, these five free tools handle larger batches, more formats, and more workflow tasks without a paid plan.
TinyPNG's free tier caps at 20 images per batch and only outputs PNG or JPEG. If you regularly compress more than 20 files, need WebP or AVIF output, or want tools beyond basic compression, there are better free options in 2026. The five alternatives below cover every workflow — from individual image fine-tuning to bulk delivery galleries to desktop-native processing.
Why People Look for TinyPNG Alternatives
TinyPNG is not a bad tool. The compression quality is solid, the interface is minimal, and millions of designers and developers have built it into their workflows. The friction points that send people looking elsewhere are consistent:
- The 20-file free limit. Photographers, e-commerce teams, and marketing agencies regularly process 50–500 images at a time. Running four or five separate TinyPNG sessions is tedious.
- No WebP or AVIF output on the free tier. Google's Core Web Vitals scoring rewards modern image formats. AVIF can cut file sizes by 40–50% versus JPEG at equivalent quality. TinyPNG Pro adds WebP; AVIF is not available on any TinyPNG plan.
- No tools beyond compression. Resize, crop, watermark, metadata strip, and client delivery are not part of TinyPNG at any tier.
If any of those are your reason for searching, one of the five tools below will solve it.
The 5 Best Free TinyPNG Alternatives
1. Optimage — Best Overall for Bulk and Delivery
Optimage is a browser-based tool that covers the complete image workflow: compress, convert, resize, crop, rotate, watermark, enhance, and strip metadata. The free tier includes up to 50 files per batch, WebP and AVIF output, and — uniquely among free tools — client delivery galleries with PIN protection and download controls.
Best for: photographers, marketers, e-commerce teams, and anyone who needs more than basic compression from a single free tool.
2. Squoosh — Best for Single-Image Quality Control
Squoosh (squoosh.app) is a Progressive Web App from the Google Chrome team. It processes one image at a time but gives you real-time side-by-side codec comparisons with full control over quality, effort level, and encoding parameters. Supports AVIF, WebP, MozJPEG, OxiPNG, and more. No sign-in, no upload to a server — it runs entirely in your browser.
Best for: developers fine-tuning a single hero image, or anyone who wants maximum quality control on a per-image basis.
3. ImageOptim — Best Mac Desktop App
ImageOptim is a free, open-source Mac application that drag-and-drop compresses images using lossless and lossy algorithms (including MozJPEG, Zopfli, and SVGO for SVGs). It strips metadata by default and requires no account. The downside: Mac only, no modern format output (no WebP or AVIF), and no online version.
Best for: Mac users who prefer a native desktop app and want zero-configuration lossless compression.
4. Caesium — Best Cross-Platform Desktop App
Caesium (saerasoft.com/caesium) is a free, open-source desktop app available for Windows, macOS, and Linux. It handles batch compression with folder-watching, quality sliders, and resize options. No cloud upload, no file count limits, no subscription. Like ImageOptim, it does not output WebP or AVIF.
Best for: users who want a native desktop app with no limits, especially on Windows.
5. Cloudinary (Free Tier) — Best for Developer Pipelines
Cloudinary is an enterprise media platform with a free tier that includes 25 GB storage, 25 GB monthly bandwidth, and dynamic image transformations via URL parameters. It supports AVIF, WebP, and automatic format selection. The free tier is genuinely useful for small development projects, but the product is aimed at developers integrating a CDN, not at designers doing manual file processing.
Best for: developers who want programmatic image optimisation integrated into a web application.

Optimage by the Numbers
Which Tool Should You Use?
The right answer depends on your workflow:
- Batch compression, modern formats, client delivery → Optimage
- Single-image fine-tuning with live preview → Squoosh
- Mac desktop, no cloud, zero configuration → ImageOptim
- Windows/Linux desktop, folder batches → Caesium
- Developer pipeline, CDN integration → Cloudinary free tier
If TinyPNG's 20-file cap is the only thing holding you back and you do not need WebP or AVIF, running two TinyPNG sessions is an option. But if you want a single tool that removes all of those limitations at no cost, Optimage is the direct upgrade.
