TinyPNG

Overview

TinyPNG is a lossy image-compression service for web users and developers who want to reduce image files in batches or through an API. It is strongest for recurring image-preparation work where resizing, conversion, and workflow integrations matter; its free web limits make it less suited to large one-off sessions.

Key features

It handles JPEG XL (JXL), AVIF, WebP, JPG, PNG, and APNG, and supports batch processing and resizing. That breadth helps when preparing assets for different formats, while lossy compression is a poor fit when images must remain unchanged. TinyPNG reports file-size reductions exceeding 85% in a visible-quality comparison, but results will depend on the image.

Unnecessary metadata is removed, and the API can retain selected copyright, location, and creation-date information. Uploaded images are accessible only to the uploader and retained for no more than 48 hours. Official WordPress and Figma plugins and a beta Zapier integration provide ways to incorporate it into publishing and design workflows.

The web and API allowances are distinct. Web Free permits 20 compressions per session, up to 5 MB per image, and three conversions per session. Free API use provides 500 compressions each calendar month; unused compressions expire rather than carrying over. API charges apply only to successful compressions beyond the allowance, with no subscription fee or minimum charge.

Pricing

Web Free costs nothing and fits occasional work within its session caps. The 5 MB image ceiling and three-conversion limit can quickly constrain larger batches.

Web Pro has custom pricing, billed yearly per user. It removes the compression cap and raises the maximum image size to 75 MB, but still allows only three conversions per session. It suits regular compression work that does not require frequent conversion. Each license gives one user access for one year, so teams need multiple licenses; moving from Web Pro to Web Ultra refunds the remaining Web Pro months.

Web Ultra also has custom pricing and is billed yearly per user. It includes unlimited compressions and conversions and accepts images up to 150 MB, making it the more suitable web tier for large files or conversion-heavy work. Its higher limits come with an individual annual license.

Developer API Free costs nothing, includes 500 compressions each month, and requires no payment details. That is a useful starting point for modest recurring workloads, but unused allowance does not roll over.

Developer API Pay Per Compression is billed monthly based on usage. The first 500 compressions each month are free; the next 9,500 cost $0.009 per compression. This avoids a subscription commitment, though costs rise with successful compression volume. The API also offers tiers for the first 500, the next 9,500, and the next 10,000 compressions, plus volume pricing: the next 10,000 monthly compressions receive a discount. Those tier prices are custom pricing. The volume-pricing plan is shown at no cost, billed monthly based on API usage.

Platforms

The listed platform is API. TinyPNG also offers a web workflow, reflected in its separate Web plans, and integrations for WordPress, Figma, and beta Zapier.

Who it's for

TinyPNG fits developers who want usage-based API billing and a monthly free allowance, and web users who need batch compression, resizing, or several image formats. Web Free is best for small sessions; Web Pro suits ongoing compression below the 75 MB ceiling, while Web Ultra is the better fit when conversions or larger files are central. Users who need lossless processing or substantial free conversion capacity should look elsewhere.

Pros and cons

• Pros: Broad format support, batch processing, and resizing cover several common asset-preparation needs.
• Pros: API billing has no subscription fees or minimum charges, and the first 500 compressions each month are free.
• Pros: Selected metadata can be preserved through the API, while uploaded images are restricted to the uploader and retained for at most 48 hours.
• Cons: Web Free is limited to 20 compressions per session, 5 MB per image, and three conversions, so it is a narrow fit for larger jobs.
• Cons: Web Pro keeps the three-conversion cap, and both paid web plans use yearly per-user licensing.
• Cons: Lossy compression may not suit work that requires unchanged image detail.

Alternatives

For a web image-compression category overview, see Image Compression Software.

Optimole may suit website operators who prefer a free plan measured by 2,000 monthly visits, with unlimited images and sites. Fastly Image Optimizer is worth considering when the listed API, Linux, and web platforms or its 100,000 free monthly image requests better match the workload.

Kraken.io offers a free 100 MB testing quota, a useful alternative for testing within a quota rather than TinyPNG's per-session web limit. Imagify may fit users who want a free monthly allowance of 20 MB, approximately 200 images, with a 2 MB per-image limit and unlimited websites.

ShortPixel Adaptive Images is a web alternative with a free 500 MB monthly CDN-traffic allowance; its Unlimited plan lists 500 GB per month for $9.99 a month. JPEGmini is another option for readers who want a seven-day trial of Pro features and a free tier limited to 50 images per day on one device.

TinyJPG has the same stated Web Free caps as TinyPNG, so those limits alone do not distinguish it. Optimizilla may suit readers who prefer a free browser-based option described as unlimited, with no registration, daily limits, or watermarks.

Verdict

Choose TinyPNG if you need lossy batch compression and resizing across multiple formats, especially through an API with a free monthly allowance and usage-based billing beyond it. Look elsewhere if you need lossless results, more generous free web conversion, or predictable pricing for a paid web plan.
