JPEG or WebP is a good balance of size and quality for photos
Photos are resized proportionally — the aspect ratio stays the same, no stretching
Advanced settings (used when "Custom" is selected)
Drag images or an entire folder here, or /
Batch selection, whole folders (incl. subfolders) · or drop anywhere on the page, or paste a screenshot with Ctrl+V · everything runs locally
Watch a folder (optional)
Pick an input/output folder and click "Start watching": images dropped into the input folder — by you, a script, or Automator — get compressed automatically with the current settings and written to the output folder. Runs entirely in this tab, no network requests.
Select an input and output folder first
Your browser doesn't support folder watching (needs a Chromium-based browser like Chrome or Edge) — you can still compress images manually with drag-and-drop or the file picker above.
Why use tinysqueeze
No paid tier, no feature restrictions, no account required.
Runs via WebAssembly in your browser — images never leave your device.
Bounded only by your computer's performance, unlike tools that cap at 5MB.
Drop in hundreds or thousands at once, or a whole folder.
Common use cases
Images are usually the heaviest part of a page. Batch-compress or convert to WebP/AVIF for visibly faster loads and lower CDN bills.
Many platforms cap image sizes and recompress anything over the limit, wrecking quality. Compress locally first and stay in control of how your images look.
Many apps can't open Apple's HEIC format. Drop photos in to batch-convert them to universal JPEG/WebP — and shrink them at the same time.
Drag in whole folders, compress in batch, and download a ZIP that keeps your folder structure — the same storage holds several times more photos.
FAQ
Are my images uploaded to a server?
No. All compression happens locally in your browser via WebAssembly — images are never uploaded and never leave your device.
Is there a file size or batch count limit?
There's no fixed limit. Since everything runs locally, file size and how many images you can process at once are only limited by your own computer's performance and memory — unlike some online tools whose free tier caps files at 5MB and batches at 20 images.
What image formats are supported?
JPEG, PNG, WebP, AVIF, HEIC/HEIF (iPhone photos), SVG, TIFF, GIF, BMP, and RAW formats from most cameras (ARW/CR2/CR3/NEF/DNG, etc.). SVG defaults to PNG, with JPEG/WebP/AVIF also available.
Will compression hurt image quality?
JPEG/WebP/AVIF use lossy compression tuned to be visually near-indistinguishable by default, and you can pick High quality or Smart auto (which searches for the just-right quality per image). In Balanced and Maximum, PNGs get color quantization (the same technique TinyPNG uses — fewer colors, visually almost identical; photo-like PNGs that can't reach the quality bar fall back to lossless); High quality keeps PNG pixels identical. After compressing, click Compare and drag the divider to check the result.
Can it convert iPhone HEIC photos to JPG?
Yes. HEIC/HEIF files are decoded locally and re-encoded — JPEG by default, or WebP/AVIF if you prefer — no need to convert them on your phone first.
Is GPS location and other photo info kept?
By default all photo info (EXIF) is removed, including GPS location. With "Keep photo info" checked, camera model, capture time and exposure settings are kept — but GPS location, serial numbers and maker notes are always removed. Color profiles (such as the Display P3 wide gamut of iPhone photos) are kept, so colors don't turn dull.
Do I need to install anything or sign up?
No. It works right in the browser — no download, no account, no ad pop-ups.
Does it work on phones?
Yes, the page is responsive and works in mobile browsers; for large batches or big files a desktop is faster.
Is this tool free?
Yes, completely free, with no paid tier or feature restrictions.
