Convert, crop, and resize images without uploading them anywhere
This tool runs entirely in your browser using the Canvas API — your files are never uploaded to a server. Drop in one or more images or PDFs, then crop, resize, recolor, convert, or download. Works offline once the page has loaded.
Supported formats
Convert from PNG, JPG/JPEG, WEBP, GIF, BMP, AVIF, SVG, HEIC/HEIF, or PDF. Convert to PNG, JPG, WEBP, ICO, or PDF. Multiple files can be edited and converted at once.
Common conversions
This tool handles the conversions people search for most — each one below goes straight to a page defaulted to that output format:
HEIC to JPG, WEBP to PNG, JPG to PDF, PDF to JPG, PNG to PDF, WEBP to JPG, PDF to PNG, PNG to JPG, SVG to PNG, AVIF to JPG, HEIC to PNG, JPG to PNG, PNG to ICO, AVIF to PNG, PNG to WEBP, Combine Images into One PDF, Combine PDF Files into One.
Why convert to ICO?
Browsers and operating systems use the .ico format for favicons and desktop shortcut icons. Most image editors don't export ICO directly, so a quick PNG-to-ICO conversion is usually the fastest way to get a working favicon file. The ICO this tool produces bundles four sizes in one file — 16×16 and 32×32 for browser tabs, 48×48 for the Windows desktop, and 256×256 for large-icon views — so the OS can pick whichever fits, instead of stretching one fixed size everywhere.
Converting HEIC photos
iPhones save photos as HEIC by default, a format most non-Apple apps and websites can't open. Drop a HEIC file in here and it decodes right in your browser — no app install, no upload — ready to convert to JPG, PNG, WEBP, or PDF.
Why convert to WEBP?
WEBP typically produces smaller file sizes than PNG or JPG at equivalent visual quality, which is why it's become the default image format served by many websites. Converting existing PNG/JPG assets to WEBP is a common step in page-speed optimization.
Converting PDFs
PDF pages can be converted to PNG or JPG — each page in the source PDF becomes its own image file. Going the other way, any image can be wrapped into a single-page PDF.
Frequently asked questions
Are my images uploaded to a server?
No. Every conversion happens locally in your browser using the Canvas API and JavaScript. Files never leave your device.
Is there a file size or file count limit?
The practical limit is your browser's available memory, not an artificial cap from this tool. Very large images or a large number of files at once may be slower depending on your device.
Can I convert multiple files at once?
Yes — drop or select several files and they'll all convert to the chosen output format in one pass. Each converted file downloads individually, except for PDF output, where you can check "Combine into one PDF" to get a single multi-page file instead.
What's the difference between JPG and PNG?
JPG uses lossy compression and no transparency, which keeps file sizes small — good for photos. PNG is lossless and supports transparency, which suits graphics, logos, and screenshots. This tool converts either way, so you can pick whichever fits the situation.
Does this support HEIC, or converting PNG to SVG?
HEIC and HEIF (the format iPhones use for photos) decode right in your browser here, so you can convert them to JPG, PNG, WEBP, or PDF like any other image. PNG-to-SVG vectorization isn't supported yet.
