Optimizilla vs TinyPNG

Optimizilla is a web image-compression tool for JPEG, PNG, WebP, GIF, and SVG files. It processes images in the browser, supports batch work, and lets users adjust quality and preview the result before saving. The compressor uses format-specific handling: JPEG quality is inferred from quantization tables with a default target of 80; PNG files become PNG8 with up to 256 colors while preserving transparency; and animated GIF optimization reduces the palette while retaining frames. Compressed images have EXIF, GPS, and camera metadata removed. The site says files are not uploaded to its servers. Its free plan is free, with no registration, daily limit, or watermark, and is described as allowing unlimited compression. The pricing page also lists a 25 MB maximum file size and batches of up to 50 files for Free. Pro costs $9 a month and includes unlimited file size and batch uploads, among other tools. Enterprise pricing is custom and not listed; its plan includes custom integrations, without naming partners.

TinyPNG is an image compression service offering lossy compression, batch processing, resizing, metadata controls and API access. It supports JPEG XL, AVIF, WebP, JPG, PNG and APNG files. Free web use allows up to 20 image compressions per session, with each image limited to 5 MB, and up to three conversions per session. The API includes 500 free compressions each month; unused free compressions reset at the start of each calendar month and do not roll over. Above that allowance, charges apply to successful compressions, with no subscription fee or minimum charge. Uploaded images are accessible only to the uploader and retained for a maximum of 48 hours. TinyPNG removes unnecessary metadata, while the API can preserve selected copyright, location and creation-date metadata. Official plugins are available for WordPress and Figma, alongside a beta Zapier integration. Web Pro offers unlimited compressions and a 75 MB per-image limit, while Web Ultra allows 150 MB images and unlimited conversions. The maker is headquartered in Hoevelaken, Netherlands.
