Output pre-selected: PNG — drop any supported image
This Studio link pre-selects PNG so you can convert to PNG immediately. Convert to PNG when you need a portable lossless still — icons, UI, documents, and editors that still think in PNG. Oxipng by default; optional Reduce palette (lossy PNG-8) for TinyPNG-style graphics.
Bring JPEG, PNG, WebP, AVIF, HEIC, GIF, SVG, and more — input format is never blocked when you convert to PNG. Encoding uses Oxipng (optional imagequant palette).
Looking for a specific source format? Use deep links like PNG to PNG or HEIC to PNG for conversion-focused copy, or stay here when your batch is mixed and you still want to convert to PNG.

Step 1
This page already set output to PNG. You can convert to PNG from JPEG, PNG, WebP, AVIF, HEIC, GIF, TIFF, BMP, SVG, and more in one queue.
Step 2
Add files or a folder. When you convert to PNG, decode and encode stay in the browser — nothing is uploaded.
Step 3
Scrub quality, optionally set a size budget (JPEG, WebP, AVIF, JXL, PNG palette search), then download one file or a ZIP after you convert to PNG.
| Topic | What you get | Note |
|---|---|---|
| Photos | PNG is huge | Prefer convert to WebP/AVIF |
| Logos | Correct | Optional palette |
| Alpha | Yes | Why people convert to PNG |
| Size budget | Supported (palette search) | Palette or resize |
| Codec | Oxipng ± imagequant | WASM |
Convert to PNG from SVG when email blocks vectors. Convert to PNG from GIF for a crisp first-frame still. Convert to PNG from JPEG when a tool refuses JPEG (the PNG will be larger).
Convert to PNG is not the smallest web photo format. Photos should convert to WebP or AVIF unless a human or printer demanded PNG.
Size budget works on PNG via palette color search. Reduce palette plus color count is the manual knob when you convert to PNG without a budget.
| Source | Before | After | Note |
|---|---|---|---|
| SVG icon | 2 KB SVG | ~1 KB PNG | Convert to PNG at 24px |
| GIF still | 90 KB GIF | ~35 KB PNG | First frame |
| JPEG photo | 2 MB JPEG | ~9 MB PNG | Larger — expected |
Drop mixed inputs. Oxipng encodes. Turn on Reduce palette only for logos/icons.
GIF first frame, TIFF first page, HEIC libheif decode — then convert to PNG from that bitmap (lossless from the decode; Camera roll HEIC itself is still lossy).
Download PNG or a ZIP. Folder trees keep relative paths.
Graphics, stickers, print-adjacent stills, PNG-only importers.
When convert to JPEG would flatten needed alpha.
Skip convert to PNG for camera photos destined for a website.
Lossless Oxipng looks identical to the decoded bitmap. Palette mode is lossy on purpose — same idea as TinyPNG / Squoosh Reduce Palette.
Icons: 32–64 colors, dither 0.
Photos accidentally as PNG: consider switching output to WebP.
Oxipng level 4 default; 6 for one-off masters.
When you convert to PNG, Image processing is 100% client-side in your browser with WebAssembly. Your photos are not uploaded, I cannot see or recover them, and sampled session replay is UI-only and does not include image pixels (media is blocked). The site still sends usage analytics and crash reports — details are on the privacy page.
Convert to PNG never uploads the bitmap. GIF still uses the first frame only. TIFF uses the first page only. HEIC decodes to pixels via libheif before you convert to PNG.
