How to batch convert images to JPG

Real folders are rarely one format. A phone shoots HEIC, a camera writes RAW, screenshots land as PNG, a designer sends WebP, a scanner produces TIFF. The moment you need to upload that folder to a form, drop it into a slide deck or hand it to someone on an older machine, the odd formats get rejected one by one. JPG is the format everything opens, which is why the fix is usually the same: turn the lot into JPGs and move on.

Converting them one at a time is slow, and it is also inconsistent — you nudge the quality slider a little differently on each file, and photos that should match end up all over the place. Doing the batch together fixes both: one output format, one quality setting, and a single download at the end. If you are unsure whether JPG is even the right target for a particular set of files, the PNG vs JPG comparison settles it in a minute.

The EditItAll image tool accepts a whole batch on one page and lets you pick a single output format for all of it:

1. Open the tool and drop in every image at once — a folder's worth, if you like. You can also browse for files or paste from the clipboard.
2. Change Output format from "Same as input" to JPG. That one choice applies to every file in the list.
3. Leave Quality at 80, or set it once for the batch. Anywhere around 75–82 is normally indistinguishable from the original on screen.
4. Optionally set a Max dimension — 4096, 2560, 1920, 1280 or 800 px — so oversized camera files come out at a sensible size as well as a sensible format.
5. Watch each row go from queued to done: every file shows its original and new size. Download files individually, or once two or more are finished, use Download all (.zip) to grab the whole batch in one go.

Change a setting after the fact and every file is re-encoded with the new value, so you never have to start over. If your batch is a single source format, the dedicated pages preset JPG for you: PNG to JPG, HEIC to JPG, WebP to JPG and TIFF to JPG — the full list is on the converters hub.

Each file's format is detected from its contents, not its name, so a batch can mix HEIC, PNG, WebP, AVIF, GIF, TIFF, BMP, PSD and camera RAW freely and still come out as a uniform set of JPGs. Three cases deserve a moment's thought before you press go:

• Transparent PNGs and WebPs. JPG has no transparency, so see-through areas are flattened onto the Flatten color — white by default. Pick a different color first if white is wrong for your images, or keep those particular files as PNG. There is more on this in why a PNG lost its transparency.
• Camera RAW. ARW, CR2, NEF and DNG files are developed automatically with standard settings — there are no exposure or white-balance sliders here. You get a faithful, shareable JPG of each frame, not a graded edit; see converting RAW to JPG in the browser for what that means in practice, or start on the CR2 to JPG page for a Canon-only batch.
• SVG. A vector file has no pixels, so it is drawn to pixels first. Set a Max dimension to control how large those JPGs come out.

One quirk worth knowing: formats a browser cannot write, such as HEIC and RAW, become JPG even on the "Same as input" setting. Set JPG explicitly anyway, so the PNGs and WebPs in the batch convert too.

File size is an output, not an input — there is no "convert to 200 KB" field. Read the before and after size on each row, adjust the quality slider once, and every file re-encodes. The readout rounds to whole kilobytes, so aim a notch under any strict upload limit. If a few JPGs still need to be smaller, run just those through the JPG compressor afterwards; which JPEG quality to use explains where the slider stops paying off.

Everything is processed right on your device: the files are never uploaded, EXIF and GPS metadata are stripped from every exported JPG, and the tool keeps working if you go offline after the page loads. There is no account, no watermark and no file limit — a large batch is constrained only by your own machine's memory, and files are processed one after another, so a few hundred camera files simply take a little longer. If the goal is smaller files rather than a different format, compressing multiple images at once is the matching guide, and the converting images cluster covers every other format pair.
