6 Best TinyPNG Alternatives
in 2026
Compared on free-tier limits, supported formats, file size caps, and privacy. Browser-only options included.
Why people leave TinyPNG
TinyPNG's compression is excellent — particularly its PNG quantizer, which is genuinely best-in-class. But the free tier caps you at 20 images per month and 5 MB per file. For anyone who shoots photos with a recent phone (10-15 MB per HEIC), or anyone running an image-heavy blog, that ceiling lasts about 30 minutes.
The Pro plan ($39/year) removes the limits but adds a recurring expense for what's ultimately a one-shot transform. The six alternatives below each solve that constraint differently — some are also free with no quota; others trade upload-required for substantial features; the privacy-conscious options process locally without ever sending bytes anywhere.
Side-by-side comparison

| Compressor.io | Free with limits; Premium $39/year | Free: 50 files/day, 10 MB each | JPEG, PNG, GIF, SVG | No |
| ShortPixel | Free 100 images/month then $4-30/mo | Free: 100 images/month | JPEG, PNG, GIF, WebP, AVIF | No |
| Optimizilla | Free | None — but slower processing | JPEG, PNG, GIF | No |

Why we built our own
None of the existing options solve all three of { free, no quota, no upload }at the same time. Squoosh comes closest but only handles one image at a time. The free server-based tools all upload your files. We built a batch-capable, browser-only compressor with format conversion (JPEG, PNG, WebP, AVIF) and target-size mode. No daily cap because there's no server tracking your usage.
No upload
Compression runs in your browser using browser-image-compression.
No quota
No 20-images-a-month wall. The tool can't count what it doesn't see.
All modern formats
JPEG, PNG, WebP, AVIF in and out. HEIC input from iPhones.
Recommendations by use case
If TinyPNG's monthly cap is hitting you
WebToolVerse Image Compressor — no quota, batch mode, AVIF support.
If you need precision tuning on a single hero image
Squoosh — Google's tool exposes encoder-level controls and a side-by-side preview that's great for getting one image exactly right.
If you're running compression on a WordPress site at scale
ShortPixel for the WP plugin and bulk processing, or stick with TinyPNG's WP plugin if you're under 100 images/month.
If you need to integrate compression into your own pipeline
TinyPNG or ShortPixel — both have stable REST APIs. Browser-only tools won't work for CI/build automation.
If you handle confidential images (medical, legal, ID)
WebToolVerse or Squoosh — only the in-browser options never see your files.
Try the WebToolVerse Image Compressor
Free, batch-capable, no upload. JPEG / PNG / WebP / AVIF + HEIC input. Quality slider plus target-size mode for pixel-perfect file budgets.
Open Image CompressorFrequently asked questions
Why are people looking for TinyPNG alternatives?
Three usual reasons: the 20-image/month free cap kicks in fast for anyone serious; the 5 MB-per-file limit blocks many phone photos; and the upload step rules out anything sensitive. Pro removes the limits but costs $39/year for what most users do a handful of times.
Is browser-based image compression as good as TinyPNG?
For lossy compression of typical web photos: yes. The browser uses libraries (mozjpeg, libwebp, AVIF encoders compiled to WebAssembly) that match server-side quality. Where TinyPNG is genuinely best-in-class is its custom PNG quantizer for graphics with large solid-color areas. For photographs, the difference is imperceptible.
Does WebP / AVIF compress better than JPEG?
AVIF compresses 30-50% smaller than JPEG at equivalent quality, and WebP about 25-30% smaller. The catch is compatibility: AVIF lacks support in Outlook and some older Android browsers; WebP is universal in 2026 except very old systems. Most modern web stacks serve AVIF with a JPEG fallback.
What about file size limits?
TinyPNG's 5 MB limit is the tightest. Squoosh, ShortPixel, and Optimizilla allow larger uploads but each has its own ceiling. Browser-based tools like WebToolVerse and Squoosh are limited only by your browser's memory — typically 1-2 GB before the tab gets sluggish, which means even 100 MP RAW conversions work.
Can I batch-compress an entire folder?
WebToolVerse, Compressor.io (Premium), ShortPixel, and Optimizilla support batch. TinyPNG's web UI handles up to 20 images at a time on the free tier; the API supports unlimited batch. Squoosh is single-image only.
Which one has an API for automation?
TinyPNG and ShortPixel both expose REST APIs. WebToolVerse, Squoosh, Compressor.io, and Optimizilla are web-only. If you need to compress images as part of a CI pipeline or build step, TinyPNG or ShortPixel are the right pick. If you just need an interactive UI, the others all win on cost.
