What this image converter does

This converter changes one image format into another in your browser. Pick the exact pair you need, from JPG to PNG to HEIC to JPG to SVG to PNG, add one file or a whole folder, choose quality and download the result. Every conversion is decoded and re encoded locally, so nothing is uploaded and there is no limit.

Photos, graphics and phone photos

Use JPG for photos you share by email or print. Use PNG for logos screenshots and any image that needs transparency and sharp edges. Use WebP and AVIF for web images where smallest file and fast loading matter. Use HEIC tools when iPhone photos will not open on Windows. The 38 converters here cover every common direction so you do not guess.

Size and quality you can count on

Lossless targets like PNG keep every pixel exactly and grow a bit larger. Lossy targets like JPG WebP and AVIF drop fine detail you rarely notice and shrink far more. Start at balanced quality, preview the result and only go lower when a size limit forces you. Keep the original file for future edits.

Private batch conversion that is actually free

Batch is first class here. Add dozens of images or a full folder and convert them together, then download a ZIP. Processing runs in web workers with codecs loaded locally, so it stays fast even for large batches and your images never leave your device. No account, no quota, no queue.

Pick the right converter in one click

Choose the pair that matches your files exactly. JPG to WebP for faster sites. PNG to WebP for transparent graphics. HEIC to JPG for Windows compatibility. TIFF to JPG for sharing scans and TIFF to WebP for web optimized scans. SVG to PNG for rasterizing icons at any size. Each page explains when that direction helps, how quality presets behave, and what happens to transparency.

Frequently asked questions

Which converter should I use for iPhone HEIC photos that will not open on Windows

Use HEIC to JPG when you need maximum compatibility for sharing and editing on Windows. HEIC to PNG is better when you want lossless editing. HEIC to WebP is best for web use. All three decode the HEIC locally and the result never leaves your browser.

Will converting JPG to PNG make text in a screenshot sharper

No, PNG will not invent sharpness. It keeps every pixel exactly so the converted screenshot will not degrade. For new work start from the sharpest source you have and export PNG. If the source is already soft, consider sharpening before converting.

Can I batch convert 100 images at once without uploading

Yes. Add the whole folder, pick the same output format and quality, and convert together. Each file is processed locally in your browser, even for 100 files, and you can download all results as a ZIP.

Does converting PNG to JPG keep transparency

No. JPG has no alpha channel so transparent areas are filled with a solid background color you choose. If you need transparency keep PNG or use WebP lossless which preserves it in a smaller file.

Is converting JPG to WebP always smaller at the same quality

Usually yes. WebP compresses photos about 25 to 35 percent smaller than JPG at similar visual quality. For graphics with flat colors the win can be larger, especially with WebP lossless.

Why does my SVG need a size when converting to PNG

SVG is vector and has no fixed pixels, PNG is raster. You choose the output width and height and the browser renders the vector at that resolution so the PNG stays crisp.

Which format should I choose for icons that must scale to any size

Keep icons as SVG when possible because they stay crisp at any size. If the platform needs raster, export SVG to PNG at the exact pixel size required or generate a favicon set from the SVG.

Do I need to download software to convert images

No. This image converter runs fully in your browser with no download and no install. You open the page, add your files, and convert. It works on any device with a modern browser and your images never leave your device.
