ToolBox Image vs TinyCompressor.
TinyCompressor and ToolBox Image are both browser-based image tools that process files entirely on your device. TinyCompressor branched into video and PDF compression; ToolBox Image doubled down on image editing depth with 14+ specialized tools. Here is how they compare.

What TinyCompressor does well
TinyCompressor launched on Hacker News in November 2025 with an ambitious scope — image compression, format conversion, video compression (via FFmpeg.wasm), and PDF compression all in one tool. Its use of Squoosh's WebAssembly codec library for images means solid compression quality, and FFmpeg.wasm brings respectable video compression to the browser. The responsive design and 11-language support show real effort in accessibility and reach. For users who need occasional video or PDF compression alongside basic image tasks, having everything in one tab is convenient.
Where TinyCompressor falls short
TinyCompressor's breadth comes at the cost of depth and polish. The most visible issue is the upload workflow — users must select a format (JPEG, PNG, WebP, etc.) before uploading, adding an unnecessary step that most modern tools auto-detect. A flagged Show HN comment confirmed the compression output was incorrect (claimed 28.75 KB, delivered the original 49 KB), raising questions about reliability in early releases. There is no batch processing — every file is handled individually — and the tool ecosystem is limited to ~4-5 features. The video and PDF compression, while notable, competes with dedicated tools that do those jobs better. And unlike ToolBox Image, TinyCompressor is closed source with no public repository, making it harder to verify its privacy claims or contribute improvements.
What ToolBox Image offers
ToolBox Image is built around a single principle: become the best browser-based image workspace on the web. Rather than stretching across file types (images, video, PDF), we focused on image depth — 13 tools that cover the full image editing lifecycle. Start with the image compressor to reduce file sizes, then switch to the resizer for platform-specific dimensions, the cropper for composition, the format converter for output flexibility, and the rotator for orientation fixes — all without leaving the browser or uploading a single file to a server.
The bulk compressor processes up to 200 images with one click — upload photos, apply consistent quality settings, download a single ZIP. Our HEIC converter handles iPhone photos directly in your browser. Target-size compression lets you specify "exactly 100 KB" and the algorithm adjusts quality to hit that number — a feature TinyCompressor lacks entirely. For choosing the right format for your project, see our best image format guide and lossy vs lossless comparison.
Breadth vs depth — the real difference
The fundamental distinction between these two tools comes down to strategy. TinyCompressor tries to be a Swiss Army knife for files — images, video, and PDFs — with a few features in each category. ToolBox Image is a dedicated image workshop with deep tooling across every common image editing task. If your primary need is video or PDF compression, and you only occasionally edit images, TinyCompressor's all-in-one approach may serve you well. But if you work with images regularly — compressing batches for ecommerce, resizing for social media, converting formats, cropping compositions — ToolBox Image's depth and polish make it the more efficient choice. Our compress for web guide explains image optimisation strategies that work seamlessly across our tool suite, keeping your images fast and sharp.
Frequently asked questions
-
Is TinyCompressor better than ToolBox Image?
TinyCompressor offers video and PDF compression (via FFmpeg.wasm) which ToolBox Image does not. However, ToolBox Image provides more image-specific tools (13 vs ~4), batch processing (up to 200 files), target-size compression, a simpler upload workflow, and open-source transparency. TinyCompressor had reliability concerns reported on launch. Choose TinyCompressor if you need video or PDF compression in the same tool; choose ToolBox Image for a more mature, focused image editing workflow.
-
Does TinyCompressor support batch compression?
TinyCompressor compresses one file at a time per session. ToolBox Image handles batch compression (up to 200 files) with consistent settings across all files and a single ZIP download. Our bulk image compressor is designed for processing multiple images at once.
-
Which tool has more features?
TinyCompressor has ~4-5 features: image compression, format conversion, video compression, and PDF compression. ToolBox Image has 13 tools including compression, bulk compression, rotator, format converter, resizer, cropper, watermark, passport photo maker, HEIC converter, signature maker, image-to-PDF, circle crop, image redactor, and metadata editor — all focused on image editing and conversion.
-
Is TinyCompressor as secure as ToolBox Image?
Yes. Both tools process everything client-side using WebAssembly — no files are uploaded to any server. TinyCompressor uses Squoosh for images and FFmpeg.wasm for video, both running locally. ToolBox Image also uses browser-native APIs and WebAssembly. Both are browser-based by design.
-
Does TinyCompressor support HEIC like ToolBox Image?
TinyCompressor supports HEIC-to-JPG conversion in its format converter. ToolBox Image has a dedicated HEIC converter for converting HEIC files from iPhones.
-
Which tool should I choose?
If you need a single tool that handles images, video, and PDFs, TinyCompressor covers more file types. If you need a deep, focused image editing workflow with batch processing, target-size compression, 13 specialized tools, and a proven track record, choose ToolBox Image. Both are free and browser-based.
