TinyPNG

Overview

TinyPNG is an image compression service for people who want to reduce image sizes through a web interface or an API. Its strongest fit is users who need batch compression, format conversion, or a way to build compression into a workflow. The free web session caps and the API’s monthly allowance make volume planning important.

Key features

TinyPNG uses lossy compression and supports JPEG XL, AVIF, WebP, JPG, PNG, and APNG. It can resize images and process batches, making it useful for preparing groups of assets rather than handling files one at a time. TinyPNG reports reducing file size by more than 85% in a visible-quality comparison; that is a substantial target, but lossy compression may not suit images that must remain unchanged.

Metadata handling is more nuanced than simple removal: unnecessary metadata is stripped, while the API can retain selected copyright, location, and creation-date fields. That gives developers a way to preserve chosen metadata while reducing the rest. Uploaded images are accessible only to the uploader and retained for a maximum of 48 hours.

The web tools and API serve different workflows. The API supports pay-per-compression billing above its free allowance, without subscription fees or minimum charges. Official WordPress and Figma plugins, plus a beta Zapier integration, can connect TinyPNG to common publishing and design processes.

Pricing

Web Free costs nothing and allows 20 compressions per session, with each image up to 5 MB, plus 3 conversions per session. It suits occasional, smaller jobs; the per-session caps make it less suitable for repeated or larger batches.

Web Pro has custom pricing, billed yearly per user. It provides unlimited compressions, a 75 MB per-image limit, and 3 conversions per session. It removes the free compression cap and raises the upload ceiling, but does not increase the conversion allowance. Web Ultra also has custom pricing and is billed yearly per user; it allows unlimited compressions and conversions, with a 150 MB per-image limit. It is the more suitable web tier when conversion volume or large files exceed Pro’s limits. Upgrading from Web Pro to Web Ultra refunds the remaining months of Web Pro.

Each Web Pro or Web Ultra license gives one user access for one year; multiple licenses can be purchased for teams. The Developer API Free plan costs nothing and includes 500 compressions each month, with no payment details required. Unused free API compressions do not roll over and reset at the start of each calendar month.

Above the free API allowance, pay-per-compression billing has no subscription fees or minimum charges. The Developer API Pay Per Compression plan is $0.01 a month, billed monthly based on usage: the first 500 compressions each month are free, and the next 9,500 cost $0.009 per compression. The Developer API Volume Pricing plan is free, billed monthly based on API usage, with a volume discount on the next 10,000 compressions per month. The listed API tiers also include the first 500 compressions, next 9,500 compressions, and next 10,000 compressions, but those tiers have custom pricing. Usage-based billing suits variable workloads better than a fixed subscription, while the monthly reset means low-use months do not build a reserve for busier ones.

Platforms

The listed platform is API. TinyPNG also provides web tools and official WordPress and Figma plugins, as well as a beta Zapier integration. Those integrations broaden its workflow reach, though the web limits differ by plan.

Who it's for

TinyPNG suits designers, publishers, and developers who need lossy image compression, batch handling, or API-based processing across supported formats. The free web plan works for modest sessions; the API free allowance suits projects that stay within 500 monthly compressions. Teams should account for per-user annual web licenses, while users with large files or frequent conversions should consider the custom-priced Ultra tier.

Pros and cons

• Pros: Broad format support, resizing, batch processing, and metadata controls cover several common asset-preparation needs.
• Pros: The API’s free monthly allowance and usage billing without subscription fees or minimum charges can suit workloads that vary from month to month.
• Cons: Free web use is capped at 20 compressions and 3 conversions per session, with a 5 MB per-image limit.
• Cons: Pro and Ultra have custom pricing, and their licenses are per user and billed yearly.
• Cons: Free API compressions reset monthly rather than rolling over, which limits the benefit of quiet months for users with uneven demand.

Alternatives

Browse Image Compression Software for more options. Choose Optimole instead if a web service with unlimited images and sites under a free plan capped at 2,000 monthly visits better matches your needs. Fastly Image Optimizer is an alternative if you want API, Linux, or web availability and a free allowance of 100,000 image requests per month. For a free desktop option, consider pngcrush on Windows, macOS, or Linux, or Caesium Image Compressor on those platforms. Kraken.io offers an API free plan with a 100 MB testing quota and a $50 a year Micro plan. ImageOptim is another API option, with a free trial and paid monthly optimization plans. Squoosh is a free web alternative, while FileOptimizer is a free option for Windows.

Verdict

TinyPNG is a strong choice for people who need dependable batch compression across modern image formats, especially when an API or publishing integration matters. Its main trade-offs are strict free web session caps and custom pricing for the annual web tiers. Choose it when those workflow tools matter more than predictable web-plan pricing; look elsewhere if you need an uncapped free web workflow or a stated price before committing.
