TinyPNG alternatives.
Compared honestly — including ours.
TinyPNG set the standard for image compression: drop in a PNG, get a dramatically smaller file that still looks right. Its limits (files and megabytes per batch) and the fact that images are uploaded send power users looking elsewhere. These seven alternatives cover the realistic options — including one that never uploads at all.
Short answer: for everyday compression (photos, screenshots, web images) Tool Pantry is free with no batch caps and nothing uploaded. Squoosh gives fine-grained control for one-off experiments; TinyPNG remains the quality benchmark.
The seven alternatives, briefly
TinyPNG's free web tier caps batch size, and the API that removes the cap is paid. Meanwhile, most compression is computationally simple — modern browsers can do it locally, which removes both the limits and the privacy question.
1. Tool Pantry — best for everyday, private file jobs
194 free tools that run entirely in your browser — files are processed on your device and never uploaded. Merge, split, rotate, sign, fill, and convert PDFs; compress and convert images, video, and audio; plus calculators and dev tools. No account, no daily caps, no watermarks. The trade-off: it focuses on everyday jobs rather than advanced PDF editing (no OCR or text re-writing), and huge files are still better handled by desktop software.
2. Squoosh — best for controlled quality experiments
Google's open-source image compressor that runs locally in your browser with fine-grained control over codecs, quality, and resizing. Excellent for one-off experiments; slower on very large batches.
3. iLoveIMG — best for a broad free image toolkit
The image sibling of iLovePDF — compress, resize, crop, convert, and watermark images. Free tier with limits and ads; upload-based.
4. Compressor.io — best for quick single-file compression
A simple, no-frills compressor for JPG, PNG, GIF, SVG, and WebP. Free with per-file size limits; upload-based.
5. Optimizilla — best for batch compression with visual control
A batch image compressor with a quality slider and side-by-side preview. Free, upload-based, with a cap on files per batch.
6. ImageOptim — best for local batch work on macOS
A free, excellent macOS desktop app that strips metadata and compresses images locally. Needs a Mac and an install; not available on the web.
7. Convertio — best for one-off conversions across file types
A general-purpose online converter covering images, documents, audio, video, and archives. The free tier has file-size limits; upload-based.

Choose TinyPNG if…
- You need the absolute best quality-per-byte and use the paid API at scale.

Choose Tool Pantry if…

Is there a free TinyPNG alternative with no batch limit?
Yes — Tool Pantry compresses images locally in your browser with no batch caps and no uploads. Quality is comparable for everyday photos and screenshots; TinyPNG's paid API still leads for automated pipelines.
Do I have to upload my files to use these alternatives?
No — and that is the main difference in this list. Tool Pantry processes everything locally in your browser: files never leave your device. The other services in these lists are server-based, so their files are uploaded. For sensitive documents, prefer a local tool.
Are these alternatives really free?
Mixed. Tool Pantry is fully free with no limits. Most others are freemium: a free tier with caps (documents per day, file size, tasks per hour) plus a paid plan. The lists above state the realistic free limits for each.
