Converts on your device — nothing is uploadedBatch Convert JPG to PNG — Free, Unlimited, In Your Browser
Convert any number of JPG files to PNG in a single pass. The output format is pre-selected, so you drop your files in and press Convert. Everything runs inside your browser — nothing is uploaded, nothing is stored, and there is no cap on how many files you can process. Free, no sign-up, no watermark.
Why Convert JPG to PNG?
PNG is lossless, so once your images are PNG they survive repeated editing and re-saving without accumulating compression artefacts. Batch converting is useful when a workflow, printer or design tool requires PNG for every asset.
Common uses: design workflows, print submissions, tools that require PNG input, images destined for further editing, archival copies.
How to Batch Convert JPG to PNG
- Add your files — drag and drop the whole selection, click to browse, or paste. Add as many as you like.
- Output is already PNG — adjust the quality if you want, or switch format at any time.
- Convert — a progress bar tracks the batch, and each row shows its new size and savings.
- Download — save files one by one, or press Download all for a single ZIP.
No File Limit, and Nothing Uploaded
Most online bulk converters cap free users at 10, 20 or 50 files, because each image has to travel to their servers and back — and several keep your files on those servers for an hour or more before deleting them. This tool converts on your own machine, so there is no artificial cap and no upload at all. That is faster, and it means personal photos and client work stay yours.
Is It Safe and Private?
Yes — every file is decoded and re-encoded locally in your browser. Your images are never uploaded, never copied to a remote server, and never stored after you close the tab.
Frequently Asked Questions
How do I batch convert JPG to PNG?
Drag and drop all your JPG files onto the upload area - the output format is already set to PNG. Press Convert, then download each file or press Download all to get one ZIP with everything. It all runs in your browser.
How many JPG files can I convert at once?
There is no fixed limit. Conversion happens on your own device, so the only constraint is your computer's memory - batches of 20 to 50 are comfortable on most machines, and a desktop handles far more. Many competing tools cap free users at 10, 20 or 50 files.
Will converting JPG to PNG improve quality?
No - and it is worth being clear about this. PNG stores the JPG's pixels losslessly, but it cannot restore detail the JPG already discarded. What you gain is no further loss from that point on, which matters if the files will be edited repeatedly.
Will the PNGs be bigger?
Usually yes, often significantly, because PNG is lossless. That is the trade-off for lossless editing. If size matters more, WebP keeps transparency and lossless-like quality at a fraction of the size.
Are my files uploaded to a server?
No. Every image is converted entirely inside your browser, so your files never leave your device. That is faster than uploading and genuinely private.
Is it free?
Completely free - no sign-up, no watermark and no file-count limit.
