Optimage vs TinyPNG in 2026 — Which Free Image Compressor Is Better?
Optimage is fully free with no file-count limit, AVIF/WebP output, and client galleries. TinyPNG's free tier caps at 20 files per batch and outputs PNG and JPEG only.
Optimage compresses images in bulk with no daily cap, outputs WebP and AVIF, and includes client delivery galleries — all at no cost. TinyPNG is the more recognisable brand and offers a cleaner single-page UI, but the free tier limits you to 20 files per batch, supports only PNG and JPEG output, and has no gallery or resize tools. If you regularly compress more than 20 images or need modern formats, Optimage is the stronger free choice in 2026.
What TinyPNG Gets Right
TinyPNG has earned its reputation. The drag-and-drop interface is genuinely frictionless, the compression algorithm (pngquant for PNG, mozjpeg for JPEG) is solid, and the brand recognition means designers and developers worldwide reach for it first. The API is well-documented and widely used in CMS plugins. For occasional single-file tasks, TinyPNG is still a perfectly reasonable choice.
The problems start when your workflow grows beyond its free limits.
Where TinyPNG Falls Short
The free tier on TinyPNG allows 20 files per upload and a maximum of 5 MB per file. There is no AVIF output. There is no WebP output (the Pro plan adds WebP conversion, but that starts at $25/year). There are no client galleries, no resize tool in the free UI, and no crop or watermark functionality.
For a photographer delivering 200 shots to a wedding client, or a marketing team processing a full product catalogue, those limits create real friction: you either pay for Pro, juggle multiple upload batches manually, or find a different tool.

AVIF and WebP Output — the Formats That Matter in 2026
Google Search now factors Core Web Vitals into rankings, and LCP (Largest Contentful Paint) is almost always an image. AVIF files are typically 40–50% smaller than equivalent JPEG files at the same visual quality. WebP sits around 25–30% smaller.
TinyPNG's free tier delivers neither. You compress a PNG and get a PNG back — smaller, yes, but still PNG. Switching to AVIF or WebP requires either the TinyPNG Pro plan or a separate conversion step.
Optimage handles compression and format conversion in a single pass. Upload a JPEG batch, check WebP output, and download files ready for <picture> tags — no extra step, no fee.
Client Galleries: A Feature TinyPNG Does Not Have
If you are a photographer or creative professional, delivering files through a raw download link or a shared Google Drive folder is a friction point for clients. Optimage includes client galleries at no cost: upload a set of images, generate a PIN-protected gallery link, and your client browses, selects favourites, and downloads at the resolution you choose.
TinyPNG is purely a compression tool — there is no delivery or sharing layer.
When to Choose TinyPNG
- You compress fewer than 20 images at a time and only need PNG or JPEG output.
- You use a WordPress or Shopify plugin that integrates with the TinyPNG API and you want to keep that integration.
- You prefer the absolute minimum UI — no configuration, no options, just drop and compress.
When to Choose Optimage
- Your batches regularly exceed 20 files.
- You need WebP or AVIF output to improve page performance scores.
- You want to resize, crop, watermark, or rotate images in the same tool.
- You deliver images to clients and want PIN-protected gallery links.
- You want to strip EXIF metadata for privacy — Optimage handles metadata removal automatically.
Verdict
Both tools are legitimate and free for basic use. TinyPNG is the better choice if you want the fastest, most stripped-back interface for occasional PNG and JPEG compression. Optimage is the better choice for any workflow beyond that: bulk batches, modern formats, integrated tools, and client delivery.
Frequently Asked Questions
Is TinyPNG really free? TinyPNG's web tool is free up to 20 images per batch and 5 MB per file. The Pro account (paid) removes those limits and adds WebP conversion.
What is the TinyPNG file limit on the free tier? The free tier allows 20 images per upload session. You can run multiple sessions, but there is no API access without a Pro key.
Does TinyPNG support AVIF? No. As of 2026, TinyPNG does not compress or convert to AVIF on any tier. Optimage supports AVIF output free of charge.
What is the best alternative to TinyPNG for bulk image compression? Optimage supports up to 50 files per batch on its free tier, with WebP and AVIF output included. For single-image fine control, Squoosh (by Google) is also worth considering.
