AllTools vs TinyPNG — Free Private Image Compression Alternative

TinyPNG vs AllTools: 20 Images/Month or Unlimited Private Compression?

TinyPNG is one of the most well-known image compression tools on the web. Drag a PNG or JPEG onto their site, and it compresses using smart lossy algorithms. The results are good — TinyPNG consistently reduces file sizes by 40-70% while maintaining visual quality. For many developers and designers, it’s the first tool they reach for.

But TinyPNG has limitations that matter at scale. Free users get 20 image compressions per month. Each image can be at most 5MB. Every image is uploaded to TinyPNG’s servers for processing. And the API (for higher volumes) costs $0.009 per image after the first 500 free per month.

AllTools’ Image Compressor takes a different approach. It runs entirely in your browser, compresses unlimited images with no monthly cap, supports modern formats like AVIF and WebP that TinyPNG doesn’t offer, and never uploads your images anywhere. Here’s the full comparison.

Quick Summary

Choose TinyPNG if: You compress fewer than 20 images per month, don’t mind uploading to their servers, and primarily work with PNG and JPEG. TinyPNG’s lossy compression algorithm for PNG is genuinely excellent.

Choose AllTools if: You compress images regularly and need more than 20/month, care about image privacy, want AVIF support for maximum compression, or need your images to stay on your device.

Feature Comparison

Where TinyPNG Wins

PNG compression quality

TinyPNG’s lossy PNG compression is genuinely best-in-class. They use a specialized algorithm that reduces the number of colors in a PNG (quantization) while maintaining visual fidelity. A 1MB PNG can often be compressed to 200-300KB with no visible difference. Their algorithm handles transparency, gradients, and subtle color variations particularly well.

AllTools’ PNG compression uses the browser’s Canvas API, which produces good results but doesn’t match TinyPNG’s specialized quantization for the PNG format specifically. For JPEG and WebP, the difference is negligible.

Developer API

TinyPNG offers a REST API for automated compression in build pipelines, CMS platforms, and deployment workflows. If you’re compressing thousands of images as part of a CI/CD process or a WordPress site, the API integrates seamlessly. AllTools is an end-user tool without a programmatic API.

WordPress plugin

TinyPNG’s WordPress plugin automatically compresses images when you upload them to your media library. For WordPress site owners, this hands-off optimization is convenient. AllTools requires manual compression before uploading to your CMS.

CDN integration

TinyPNG integrates with Cloudflare and other CDNs for on-the-fly image optimization. For high-traffic websites, this means images are compressed automatically at the edge. AllTools is a standalone tool, not a CDN integration.

Where AllTools Wins

Unlimited compressions — no monthly cap

TinyPNG limits free users to 20 images per month. For a blog post with 10 screenshots, that’s half your monthly budget on a single article. A product catalog shoot? You’ll hit the limit on day one.

AllTools has no monthly limit, no daily limit, and no per-session limit. Compress 5 images or 500 — it’s all free, always. The practical limit is your device’s memory, which handles hundreds of images without issues.

AVIF — the format TinyPNG doesn’t support

AVIF (AV1 Image File Format) is the most efficient image format available today. Compared to other formats:

AVIF delivers 30-50% smaller files than WebP at equivalent visual quality. For websites optimizing Core Web Vitals and page load speed, AVIF is a significant advantage. AllTools supports both AVIF compression and conversion. TinyPNG supports JPEG, PNG, and WebP — but not AVIF.

Images never leave your device

Every image you compress on TinyPNG is uploaded to their servers, processed, and returned. For many images this is fine. But for some, it matters:

• Personal photos — Family photos, private moments, images you wouldn’t post publicly
• Client work — Product photos under NDA, unreleased marketing materials
• Medical images — Diagnostic images, patient photos
• Identity documents — Passport scans, ID photos, signatures

AllTools compresses using the Canvas API in your browser. The image is read from your filesystem, processed in browser memory, and the compressed result is downloaded directly. No network transmission, no server processing, no retention period.

Adjustable quality control

TinyPNG automatically determines the compression level. You get what their algorithm decides is optimal — no adjustment possible. This works well in most cases but offers no control when you need a specific file size target.

AllTools provides an adjustable quality slider. Need a 50KB image for a specific web requirement? Slide the quality down until you hit the target. Need maximum quality with minimal compression? Keep the slider high. The before/after comparison slider lets you visually verify the tradeoff before downloading.

No file size limit

TinyPNG limits free uploads to 5MB per image. Modern smartphones produce photos in the 5-15MB range, and DSLR photos easily exceed 20MB. If you’re compressing source photos rather than already-optimized web images, TinyPNG’s 5MB cap forces you to pre-resize before compressing — an extra step.

AllTools has no file size limit. Browser memory is the only constraint, and modern devices handle images of 50MB+ without issues.

The Bottom Line

Use TinyPNG when:

• You compress fewer than 20 images per month
• You need the best possible PNG compression (TinyPNG’s quantization is excellent)
• You need API integration for build pipelines or CMS
• You use the WordPress plugin for automatic optimization
• Image privacy isn’t a concern for your use case

Use AllTools when:

• You compress more than 20 images per month
• You want AVIF support for maximum compression
• Image privacy matters (personal photos, client work, medical)
• You need adjustable quality control, not just automatic
• You need images to stay on your device
• You need other tools beyond compression (resize, crop, convert)

The practical recommendation

For casual compression of a few web assets, TinyPNG’s automatic optimization is convenient. For anything beyond that — regular compression workflows, privacy-sensitive images, large files, modern formats, or adjustable quality — AllTools is the more capable and flexible choice, at no cost.

FAQ

Is AllTools compression quality as good as TinyPNG?

For JPEG and WebP, the compression quality is comparable. Both tools produce excellent results at typical compression ratios. For PNG specifically, TinyPNG’s specialized quantization algorithm has a slight edge in finding the optimal color palette reduction. However, AllTools’ AVIF support achieves smaller file sizes than any format TinyPNG supports.

Can I compress images in bulk?

Yes. AllTools processes images one at a time through the interface, but you can use multiple browser tabs to compress several images simultaneously. There’s no daily or monthly limit. TinyPNG allows batch uploads of 20 images at once on the web, but limits you to 20 per month on the free tier.

What is AVIF and why does it matter?

AVIF is a modern image format based on the AV1 video codec. It offers 30-50% better compression than WebP and 40-50% better than JPEG at the same visual quality. For websites, this means faster load times, better Core Web Vitals scores, and lower bandwidth usage. Browser support is strong — Chrome, Firefox, Edge, and Safari 16+ all support AVIF.

Does TinyPNG strip EXIF data?

Yes, TinyPNG automatically removes EXIF metadata during compression. AllTools also offers EXIF removal through the dedicated Image EXIF Remover, giving you explicit control over which metadata is removed. If you want to keep EXIF data while compressing (for archival purposes), AllTools gives you that option.

Why is there no AllTools API?

AllTools is designed as an end-user tool that runs in the browser. Adding an API would require server-side processing, which contradicts the core privacy principle (files never leave your device). For programmatic image optimization, tools like TinyPNG’s API, Sharp (Node.js), or ImageMagick are designed for that use case.
