Resize Images in Bulk
Set exact pixels or a percentage — every image is resized locally with high-quality scaling.
Your images NEVER leave your device. All processing happens locally in your browser.
Drop images to resize in bulk
By exact pixels or percentage — aspect ratio always preserved
HEIC and SVG inputs are auto-converted (HEIC→JPG, SVG→PNG) when kept.
Applies to lossy formats: JPG, WebP, AVIF. Lower = smaller file.
Frequently asked questions
Are my images uploaded to a server?
No. PicShift runs 100% inside your browser using WebAssembly and Canvas. Your images never leave your device — you can even disconnect from the internet after the page loads.
How does PicShift open HEIC and TIFF files?
A full ImageMagick engine compiled to WebAssembly loads on demand (about 14 MB, once). It decodes HEIC/HEIF photos from iPhone and TIFF scans locally, then re-encodes them to the format you choose.
Is there a limit on the number of images?
No artificial limits. Drop 100+ images at once — a pool of Web Workers processes them in parallel without freezing the page, and you can grab everything as one ZIP.
Does PicShift remove EXIF metadata?
Yes. Converted images are re-encoded from raw pixels, which strips EXIF data including GPS location — an extra privacy win over many online converters.
