All docsWhy I Built PicShift
The motivation behind a local-only, privacy-first image converter and how it is continuously improved.
Privacy and Local Processing
How PicShift keeps image processing on-device and what data is or is not used.
Format Compatibility Guide
A practical compatibility matrix for JPG, PNG, WebP, HEIC/HEIF, and AVIF.
Image Quality vs File Size
How to pick quality settings for the best trade-off between visual clarity and size.
Why Output Size Can Increase

All Tools
Resize Images
Resize photos for websites, forms, email, or social posts. Pick a preset (1920px, 1080px, 50%) or enter custom pixels — all processing stays on your device.
Compress Images
Shrink file sizes while keeping the picture usable for web or email. Move the quality slider and check the side-by-side preview before you download.
Remove Image Metadata
Strip hidden metadata from your photos before sharing. GPS coordinates, camera model, timestamps, and software tags are embedded in most images by default. This tool removes all of it locally in your browser — the image never leaves your device.
HEIC to JPG
Convert your iPhone HEIC photos to JPG format instantly. Everything happens in your browser — your photos never leave your device.
HEIC to PNG
Convert your iPhone HEIC photos to lossless PNG format. All processing happens locally in your browser.
HEIC to WebP
Convert your iPhone HEIC photos to the modern WebP format. WebP offers 25-34% smaller files than JPG at the same quality.
HEIC to AVIF
Convert iPhone HEIC photos to AVIF for modern delivery pipelines that prioritize smaller transfer size.
HEIF to JPG
Convert HEIF to JPG when you need a version that opens more reliably in older apps, upload forms, and everyday sharing tools. JPG is still the safest fallback when HEIF support is inconsistent.
HEIF to PNG
Convert HEIF images to PNG when you need lossless output for editing, design handoff, or archiving workflows.
HEIF to WebP
Convert HEIF images to WebP for modern web delivery workflows that require smaller transfer sizes.
HEIF to AVIF
Convert HEIF images to AVIF when your target platform supports AVIF and maximum size reduction is a priority.
WebP to JPG
Convert WebP images to the universally compatible JPG format. All processing happens locally in your browser.
WebP to PNG
Convert WebP images to lossless PNG format. Perfect for when you need transparency or lossless quality.
PNG to JPG
Convert PNG images to JPG to reduce file size. Great for photos saved as PNG that don't need transparency.
PNG to WebP
Convert PNG to WebP when you want smaller transparent web images without giving up alpha support. This is one of the easiest ways to speed up image-heavy pages and UI assets.
JPG to PNG
Use this JPG-to-PNG converter when you need a lossless container for edits or annotations. It does not recover quality already lost in the source JPG, but it helps avoid extra degradation on every future save.
JPG to WebP
Convert JPG images to the modern WebP format for 25-34% smaller file sizes at the same visual quality.
JPG to AVIF
Convert JPG to AVIF when your target platform supports AVIF and you want a smaller modern image format. This is especially useful for performance-focused web delivery where every KB matters.
PNG to AVIF
PNG files are lossless and large. AVIF compresses them down to a fraction of the size — often 50-70% smaller — while keeping transparency intact. If the image is going on a website, this is one of the biggest performance wins available.
WebP to AVIF
Convert WebP images to AVIF when your target platform supports AVIF and size reduction is a priority.
AVIF to JPG
Convert AVIF images to the universally compatible JPG format. All processing happens locally.
AVIF to WebP
Convert AVIF images to WebP when your target platform requires wider compatibility while keeping modern compression.
AVIF to PNG
Convert AVIF images to lossless PNG format. Perfect for preserving maximum quality.
