Image tools

Image tools that don't upload your photos

The hub for every SnapToolz image tool — sized around the three questions that decide any image: how big should the file be, what format does it need, and what should it show. Whether you're prepping photos for the web, hitting an upload limit, cleaning metadata before you share, or grabbing colours for a design, this page points you to the right one.

  • No uploads — files stay on your device
  • WebAssembly fast
  • Works offline
  • 100% free, no sign-up

Image optimization, end to end — format, quality and dimensions

Start here: which image tool for which job

Three levers decide every image — format, dimensions, and quality — and each has its own tool. The most common mistake is reaching for quality when the real problem is size. Find your task, follow the link:

Resize before you compress — capping dimensions is the single biggest win for web images.

Who this hub is for, and where to begin

Bloggers and store owners trimming page weight, job applicants squeezing a photo under a form's KB cap, iPhone users converting HEIC so a colleague can open it, and designers lifting a palette from a reference shot — this is the shared starting point. If your photos are personal and you'd rather they not pass through someone else's upload queue, that's exactly the case these tools are built for.

Not sure where to begin? For most web work, Resize Image first (capping dimensions is the biggest single win), then Compress Image. Hitting a hard size limit on a form? Compress Image to Size targets an exact KB figure. Sharing publicly? Run Remove EXIF so location and camera data don't tag along.

For the format decision itself — JPG vs PNG vs WebP vs AVIF — and the full end-to-end pipeline, the Image Learning Center hub has the deep dive. This page is the map; the tools and the hub hold the detail.

Frequently asked questions

  • Are my files uploaded anywhere?

    No. Every SnapToolz tool runs entirely in your browser using JavaScript and WebAssembly. Files are read locally, processed in memory, and the result is offered as a download. There is no backend.

  • Which image formats are supported?

    JPG, PNG, WebP, HEIC (iPhone photos), AVIF and GIF — input and output where the format makes sense. The convert tool transcodes between any pair.

  • Can I batch-compress photos?

    Yes — drop multiple files at once into Compress Image. Each result is shown with its savings percentage so you can verify quality before downloading. Resize, Convert and EXIF Remover all support batches too.

  • Will I lose quality?

    Only if you pick aggressive settings. The default compression level is visually-lossless on most photographs. Use the resize tool's high-quality bicubic mode for resampling without softness.

  • What's the best tool for shrinking images to a specific KB target (50KB, 100KB, 200KB)?

    Compress Image has KB-target presets that combine intelligent resizing with quality tuning to land within the target size. Useful for online forms, KYC uploads, and email attachments where there's a hard upload limit.

  • Does the EXIF Remover strip GPS coordinates?

    Yes — re-encoding via canvas inherently removes EXIF, including GPS. For explicit byte-level stripping (no re-encode, no quality loss), use the dedicated EXIF Remover tool which strips metadata from JPEGs without touching pixel data.

  • Is everything free?

    Yes — every tool in this category and on the entire site is free with no sign-up, no daily limit, and no watermark.
