Best Image Compressors Compared: other image tools, Squoosh, iLoveIMG, FyleTools

Image compression is one of the most common file tasks on the web — and there are more tools to do it than ever. But they differ significantly in how they work, what formats they support, whether they upload your images to a server, and whether they hit you with limits or paywalls. This comparison covers four popular options: other image tools, Squoosh, iLoveIMG, and FyleTools — so you can make an informed choice.

other image tools — The Popular Choice with Server Processing

other image tools (which also handles JPEG under the brand TinyJPG) is probably the most widely known image compression tool. It uses a smart lossy compression algorithm that achieves impressive file size reductions while maintaining visually acceptable quality. The interface is simple: drag, drop, download. The catch is that it uploads images to other image tools's servers for processing.

other image tools's free tier limits you to 20 images per session and 5 MB per file. The API (for developers) has a free tier of 500 compressions per month. For regular users with many images or large files, these limits become obstacles quickly. A paid API plan is available but requires sign-up and monthly fees.

• Cost: Free with limits (20 images/session, 5 MB max)
• Privacy: Images uploaded to other image tools servers
• Formats: PNG, JPEG, WebP
• Processing: Server-side
• Best for: Occasional PNG/JPEG compression, developers using the API

Squoosh — Google's Local Compression Tool

Squoosh, built by Google Chrome Labs, is a browser-based image compression tool that processes images locally using WebAssembly. It is genuinely private — your images never leave your browser. Squoosh supports an impressive range of output formats including WebP, AVIF, OxiPNG, MozJPEG, JPEG XL, and others, with full control over compression settings.

The limitation of Squoosh is that it is designed as a single-image tool. You compress one image at a time with a side-by-side quality/size comparison interface. This is excellent for precise, manual compression of important images — a hero image for a website, a photo for a portfolio — but impractical for batch processing multiple images. Squoosh also does not include any other file tools; it is purely an image compressor.

• Cost: Free
• Privacy: Local processing — no upload
• Formats: JPEG, PNG, WebP, AVIF, JPEG XL, and more
• Processing: Browser-side WASM
• Best for: Single-image fine-tuning with format control

iLoveIMG — Feature-Rich but with Upload Limits

iLoveIMG is the image-focused sibling of other online tools. It offers image compression, resizing, cropping, format conversion, and several other operations. The free tier is functional but limited: file size caps, daily operation limits, and server-side processing. Premium plans start at around €3-5/month for unlimited operations.

Like other iLove products, your images are uploaded to their servers for processing. For personal photos and non-sensitive images, this may be acceptable. For images of documents, screenshots with sensitive information, or any professionally confidential visual content, server uploads create unnecessary risk.

• Cost: Free tier with limits + paid plans from ~€4/mo
• Privacy: Images uploaded to EU servers
• Formats: JPEG, PNG, GIF, WebP, and others
• Processing: Server-side
• Best for: Users who need image + document tools in one place occasionally

FyleTools — Private, Unlimited, WebAssembly-Powered

FyleTools compresses images using a WebAssembly engine compiled from Rust, running entirely in your browser. Like Squoosh, no images are ever uploaded to a server. Unlike Squoosh, FyleTools supports batch compression of multiple images, integrates with a full toolkit (resize, convert, crop, PDF tools, audio/video conversion), and has no limits on file count or file size beyond browser memory.

The compression quality is excellent for JPEG and PNG — leveraging the same high-performance Rust image processing libraries used in production systems. WebP support is included. The interface is streamlined for fast bulk processing.

• Cost: Free, unlimited
• Privacy: Local WASM processing — no upload
• Formats: JPEG, PNG, WebP, GIF, HEIC, and more
• Processing: Browser-side WASM
• Batch support: Yes
• Best for: Batch compression with privacy, combined image+PDF workflow

Head-to-Head Comparison

For a single image where you want maximum control over quality vs. size trade-off and want to choose from a wide range of modern formats including AVIF, Squoosh is the best dedicated tool. For batch JPEG/PNG/WebP compression with privacy and no limits, FyleTools is the better choice. other image tools is convenient and produces good results but uploads your images and imposes session limits. iLoveIMG is a reasonable option for combined image and document workflows but has upload and limit issues similar to other image tools.

The Privacy Angle

Two of these four tools (other image tools and iLoveIMG) upload your images to external servers. For most photographs and web graphics, this is not a meaningful privacy risk. But people frequently take screenshots of financial records, personal conversations, medical results, or sensitive documents and want to compress them to share. For those images, a local processing tool is the only safe choice. Both Squoosh and FyleTools guarantee that your images never leave your device.
