Pixotter vs TinyPNG: Full Comparison

Feature Comparison

Why the Comparison Matters

TinyPNG is the default image compression tool for most web professionals. It has been around since 2014, processes over a billion images per year, and its WordPress plugin has over a million active installs. If you search "compress image" or "optimize PNG," TinyPNG is almost certainly in your results. Pixotter takes a fundamentally different approach to the same problem — and understanding the architectural differences helps you pick the right tool for your workflow.

The core distinction is not feature count. Both tools compress images well. The difference is in how they handle the workflow around compression.

TinyPNG is a server-side, single-operation tool. You upload images to their servers, they compress them, you download the results. If you also need to resize those images, you open a different tool (or use TinyPNG's API, which does support resize). If you also need to convert formats, that is a third step. Each step is a separate upload-process-download cycle.

Pixotter is a client-side pipeline tool. You drop images into the browser, select every operation you need — compress, resize, convert, crop — and run them all in one pass. The images never leave your device. There is no upload, no download delay, and no server queue.

This is not a cosmetic difference. For someone compressing a single PNG once a week, TinyPNG and Pixotter produce similar results in similar time. For someone processing 15 product photos that all need compression to WebP at 800x800 pixels, the pipeline saves real minutes per batch. The upload-download overhead on TinyPNG — especially with larger files or slower connections — adds up fast when you are doing it three times per image.

Privacy and data handling. TinyPNG uploads your images to their servers, where they are stored for up to 48 hours before automatic deletion. Their privacy policy is straightforward about this — images are processed server-side and cached temporarily. For most casual use, this is fine. For anyone processing client photos, medical images, legal documents with embedded images, or anything covered by an NDA, sending files to a third-party server introduces a compliance question that client-side processing sidesteps entirely. Pixotter processes everything in your browser using WebAssembly (wasm-vips). Your images stay on your machine — there is no server to trust and no retention period to worry about.

Compression quality. TinyPNG uses smart lossy compression with a proprietary algorithm optimized for PNG and JPEG. It strips unnecessary metadata and reduces color palette depth where possible, achieving typical reductions of 40-70% with minimal visual degradation. Pixotter uses wasm-vips with MozJPEG for JPEG and standard libvips encoders for other formats, plus a quality slider that gives you direct control over the compression-quality tradeoff. TinyPNG's automatic approach is convenient — you upload, it picks the settings. Pixotter's slider approach gives more control — you decide exactly how much quality to trade for file size. Neither approach is categorically better; they serve different use cases.

Format support. TinyPNG started with PNG (the name gives it away) and later added JPEG, WebP, and AVIF. Pixotter supports JPEG, PNG, WebP, AVIF, TIFF, GIF, and BMP input, with conversion between most of these formats. If you work primarily with PNG and JPEG — which covers the vast majority of web images — both tools have you covered. If you regularly handle TIFF from print workflows, GIF animations, or need to convert between multiple formats in one session, Pixotter covers more ground without leaving the browser.

WordPress integration. This is TinyPNG's strongest advantage, and it is significant. The TinyPNG WordPress plugin (Compress JPEG & PNG images) has over a million active installs and integrates directly into the WordPress media library. Upload an image to WordPress, and TinyPNG automatically compresses it in the background. Pixotter does not yet have a WordPress plugin. If your workflow is centered on WordPress and you want set-it-and-forget-it compression, TinyPNG is the established solution. Pixotter is the better choice for manual batch processing outside of WordPress, but it requires you to compress before uploading to your CMS.

API comparison. Both tools offer APIs for developers. TinyPNG's API is mature, well-documented, and battle-tested — it supports compression, resize, and format conversion with a simple REST interface. Pricing is per-compression: the first 500 per month are free, then $0.009 each. Pixotter's API is newer, with a free tier of 500 operations per month and usage-based pricing above that. For high-volume automated pipelines, TinyPNG's API has a longer track record. For new projects evaluating options, the free tiers are comparable and both APIs are straightforward to integrate.

Pricing

Bottom line on pricing: TinyPNG's free tier is generous for light users but imposes per-session limits that matter for batch workflows. Pixotter's free tier has no per-session caps. For WordPress users, TinyPNG's plugin pricing ($39/yr for 10,000 images/month) is reasonable and has no current Pixotter equivalent. For manual web-tool usage, Pixotter offers more for free.
