Why look for TinyPNG alternatives?

TinyPNG free tier limits to 500KB per file and 20 files per month. Pro is $39/year. Many users want unlimited free use, browser-side privacy (TinyPNG uploads to their servers), or batch processing without sign-in.

Are browser-side compressors as good as TinyPNG?

TinyPNG uses a custom compression algorithm (likely fine-tuned MozJPEG plus PNG-specific logic) that's 10-20% better than browser canvas re-encoding. For most use cases (web, email, social), the difference is invisible. For maximum compression on production assets, TinyPNG still wins. For privacy and unlimited use, browser-side wins.

What's the difference between lossy and lossless image compression?

Lossy (JPG, WebP, AVIF) discards some image data to save space — irreversible but typically invisible at 80-90% quality. Lossless (PNG, lossless WebP) preserves every pixel — larger files. TinyPNG and most alternatives are lossy. For graphics with sharp edges (logos, screenshots), lossless or PNG is safer.

Is Squoosh by Google a TinyPNG alternative?

Yes. Squoosh is a free browser-side image compression tool from Google's Chrome team. It supports MozJPEG, WebP, AVIF with fine-grained quality controls. Excellent for one-off optimization. Lacks batch processing and an explicit ad-free privacy stance.

Which alternative is best for batch processing?

Pickrack and ImageOptim (Mac desktop) handle batch best. Pickrack runs in the browser (no install) and processes a folder of images. ImageOptim is Mac-only but uses multiple compression engines for best results. Squoosh handles one image at a time.

Do these alternatives support AVIF?

AVIF is the newest format (~50% smaller than JPG at same quality). Browser support: Chrome (since 2020), Firefox (2021), Edge (2022). Safari has partial support. Pickrack, Squoosh, and ImageOptim all support AVIF. TinyPNG added AVIF in 2023.

Will image compression strip my EXIF metadata?

Most browser-side compressors strip EXIF as a side effect of canvas re-encoding. This is actually a privacy benefit (camera and GPS data is removed). To preserve EXIF, use a desktop tool like ImageOptim with metadata-preserve mode or run exiftool to copy metadata after compression.

Should I use lossless or lossy compression for screenshots?

Screenshots compress best as PNG (lossless) because they have sharp edges, gradients of similar colors, and large solid-color areas. JPG can introduce visible artifacts on text and UI elements. For maximum compression of screenshots, use lossless WebP — same quality as PNG at typically 30% smaller size.

Free TinyPNG Alternatives 2026: 5 Tools That Match the Quality

TinyPNG has a 500KB-per-file free limit and 20 files/month before showing the Pro upgrade prompt. At $39/year for Pro, it's reasonable, but many users want unlimited free use without uploading their images.

This post tests 5 free alternatives, including 3 that run entirely in your browser (zero upload).

TinyPNG file size limit warning — TinyPNG's quiet wall: 5 MB ceiling per file on the free web tool and 20 images per batch. Hit the wall and the upgrade prompt appears.

1. Pickrack Image Compressor (browser-side)

pickrack.com/tools/image/image-compressor

Pickrack Image Compressor UI showing quality slider and before/after file size — The Pickrack compressor in action — JPG quality slider on the left, file size delta visible on the right. Browser-side, nothing uploads.

Cost: Free, unlimited
Privacy: Runs in your browser via Canvas API + toBlob. Image never uploads.
Batch: Yes, ZIP download
Formats: JPG, PNG, WebP input. JPG, PNG, WebP output.
Compression quality: 80% JPG produces images visually identical to original at ~70% smaller size

Pros:

No file size limit (other than ~50MB browser memory practical limit)
Real-time before/after preview with quality slider
Batch process multiple images at once
Convert format while compressing (JPG → WebP for ~30% additional savings)
No signup, no daily quota

Cons:

Browser canvas encoder is ~10-15% less efficient than TinyPNG's proprietary algorithm at maximum compression
Doesn't preserve EXIF metadata (this is also a privacy benefit)
No AVIF output yet (input only)

2. Squoosh (Google Chrome team)

squoosh.app

Cost: Free, unlimited
Privacy: Browser-side
Batch: One image at a time
Formats: All major (MozJPEG, WebP, AVIF, PNG)

Pros:

Side-by-side before/after with finger-grain quality control
Multiple compression engines including MozJPEG (the gold standard)
Open source (Apache 2.0)

Cons:

One image at a time (no batch)
UI feels engineering-built, less polished for non-devs
AVIF encoding is slow (10-30 seconds for typical photos)

Best for: developers and designers who want to tune compression quality precisely on hero images.

3. ImageOptim (Mac desktop)

imageoptim.com

Cost: Free desktop app, Mac only
Privacy: Local processing
Batch: Yes, drag-drop folder
Formats: JPG, PNG, GIF, SVG

Pros:

Multiple compression engines (PNGOUT, OptiPNG, MozJPEG, Pngcrush) — runs all and picks the best
Local processing — verifiable privacy
Preserves EXIF if configured

Cons:

Mac only (no Windows or Linux)
Desktop app (install required)
No web interface for occasional users

Best for: Mac users who optimize many images regularly.

4. Compressor.io

compressor.io

Cost: Free 10/session, then prompts upgrade
Privacy: Cloud upload
Batch: Limited to ~10/session in free tier

Pros:

Polished UX
Lossless mode preserves quality

Cons:

Quota nudges upgrade quickly

We don't recommend Compressor.io as a main tool — it has the same downsides as TinyPNG (cloud upload, quota) without TinyPNG's compression quality.

5. TinyPNG (the reference)

tinypng.com

TinyPNG Pro pricing page showing $39 per year for individuals — TinyPNG Pro pricing as captured. Unlimited compressions and Photoshop plugin behind the $39/year tier.

Polished UX, mobile-friendly
Adobe Photoshop plugin for designers

Cons:

Uploads images to their servers (no browser-side mode)
Free tier nudges upgrade aggressively
$39/year for unlimited

If you're publishing production website assets where maximum compression matters and you don't mind the upload model, TinyPNG is still excellent. For everything else, the alternatives above suffice.

Compression test results

Same source JPG compressed by 5 different tools shown side by side — Same 4 MB source JPG (a portrait at 4000×3000) compressed by all five tools at visually-lossless target. Output crops shown at 100% pixel zoom for direct comparison.

Same 4MB JPG photo, same target quality (~visually lossless):

Tool	Output size	Reduction	Notes
TinyPNG	980KB	75%	Best result, edge sharpness preserved
Pickrack (Q80)	1.2MB	70%	Visually identical at 100% zoom
Squoosh (MozJPEG Q80)	1.05MB	74%	Similar to TinyPNG with manual tuning
ImageOptim	1.1MB	72%	Multiple engines, picks best
Compressor.io	1.3MB	67%	Default settings

For 95% of use cases, the difference between these is invisible. Pick based on privacy and workflow needs, not absolute compression efficiency.

How to choose

Use Pickrack if:

You want unlimited free batch processing
You care about browser-side privacy
You like having compression + resize + format conversion in one place
You don't want to install desktop software

Use Squoosh if:

You want maximum manual control over compression quality
You're optimizing hero images for a website where every byte matters
You only do occasional one-off compressions

Use ImageOptim if:

You're on Mac and process many images
You want absolute best compression with multiple engines

Use TinyPNG if:

You're optimizing production website assets at scale
You need their Photoshop integration
$39/year is in budget and you don't mind upload

Use Compressor.io: rarely. Mostly redundant with the better alternatives.

What about WebP and AVIF?

If you can use WebP or AVIF (every modern browser supports both since 2022), you'll typically save another 20-30% over JPG at equivalent quality:

JPG → WebP: ~25-30% smaller, same quality
JPG → AVIF: ~40-50% smaller, same quality (slower to encode)

Pickrack's Image Converter handles all four formats. For web deployment, prefer WebP (broader support) or AVIF (smaller, modern only).

Conclusion

TinyPNG is excellent and worth $39/year if you optimize production assets at scale. For everyone else — students, freelancers, casual users, anyone with privacy concerns — Pickrack's image compressor offers unlimited free use with verifiable browser-side privacy.

The compression quality gap is small (10-15%) and rarely visible. The privacy gap is large and verifiable.
