picconv vs TinyPNG: which should you use?
TinyPNG is not a converter - it does one thing, image compression, and it does that one thing extremely well. Comparing it with a broad toolbox is only useful if you look at the specific job.
The short answer
If your only goal is the smallest possible PNG or JPEG at the best visual quality, and you are fine with uploading, TinyPNG is likely to beat us on the same source image. That is their entire business and they are good at it. If you need an API for an automated pipeline, they have one and we do not.
If you need a specific file size limit ("under 200 KB"), a format conversion, a HEIC photo from an iPhone, EXIF removal, or a PDF - or if the image should not be uploaded at all - picconv covers those jobs. The two tools are complements rather than substitutes.
- Smallest possible PNG/JPEG, quality is the only metric → TinyPNG
- Automated compression inside your own pipeline (API) → TinyPNG
- Must hit an exact file size limit for an upload form → picconv
- HEIC, AVIF, WebP conversion, EXIF removal or PDFs → picconv
- Image must not leave your device → picconv
Side by side
| picconv | TinyPNG | |
|---|---|---|
| Files uploaded to a server | No - processed in your browser | Yes |
| Primary purpose | Broad toolbox: 86 tools | Image compression, and only that |
| Compression quality on the same image | Good, but not specialised | Among the best available |
| Target an exact file size (for example 200 KB) | Yes, dedicated tools | No - quality-based only |
| Format conversion (HEIC, AVIF, WebP, PNG, JPG) | Yes, including iPhone HEIC | Limited; compression-focused |
| PDF tools | 22 PDF tools | None |
| Developer tools (JSON, hashing, encoding) | 18 tools | None |
| API for automation | No | Yes |
| Resize, crop, rotate, watermark, EXIF | Yes | Basic resize and crop |
| Account and usage limits | No account, no task limit | Free tier with limits; paid plans |
| Works offline once loaded | Yes | No |
| Languages | 14 | Fewer, with an English-first interface |
Where TinyPNG is the better choice
- Better compression on the same image. Their pipeline squeezes PNG and JPEG harder than a general-purpose browser encoder typically does. If the only question is "smallest file, best quality", they usually win, and pretending otherwise would be dishonest.
- An API. For a build pipeline, a CMS plugin or a batch job processing thousands of images, an API is the right tool. We have none.
- A settled, single-purpose product. No format decisions, no option paralysis: drop the file, get a smaller one.
Where picconv is the better choice
- Exact file size targets. Upload forms ask for "under 200 KB" or "maximum 1 MB", not "optimally compressed". Several of our tools compress to a specified size and reduce dimensions if quality alone cannot get there.
- Format conversion, not just compression. HEIC from an iPhone, AVIF, WebP, PNG and JPG in both directions, with transparency handled where the format supports it.
- PDFs. 22 PDF tools - merge, split, organise, compress, extract text and images, fill forms, add page numbers, watermark, protect and unlock. TinyPNG does not touch PDFs.
- Metadata removal. EXIF, including GPS coordinates, can be stripped without touching a single pixel.
- No upload. For photos of documents, ID cards or anything taken at home, not transmitting the file is a different privacy posture - verifiable in the browser's Network panel.
- Developer utilities too, such as JSON formatting, hashing, Base64 and JWT decoding, in the same place.
What about other options
iLovePDF and Smallpdf cover the PDF side if you want one platform for everything, though both upload. If your goal is the smallest possible image and uploading is acceptable, TinyPNG remains a reasonable first stop - or use both: theirs for archival compression, ours when a size limit or a format conversion is the actual requirement.

Frequently asked questions
Does TinyPNG compress better than picconv?
Usually yes, on the same image and with only visual quality as the metric. TinyPNG is a specialist compressor; our tools are general-purpose encoders. Where we differ is the requirement: if a form demands a specific kilobyte limit, we optimise for that number, which is a different objective.
Can picconv compress to an exact size like 200 KB?
Yes. There are dedicated target-size tools for 50 KB, 100 KB, 200 KB, 500 KB and 1 MB, plus a general "compress to size" tool. They lower quality toward the target and reduce dimensions if quality alone cannot reach it.
Is picconv a TinyPNG alternative for web images?
For the compression step alone, not really - TinyPNG is better at that specific task. For everything around it (converting HEIC or AVIF, hitting a size limit, stripping EXIF, handling a PDF), picconv covers jobs TinyPNG does not attempt.
Why does picconv not have an API?
Because the conversion happens in the visitor's browser - there is no server to call. An API would require shipping files to a backend, which is exactly the architecture this site avoids.
Which is better for privacy?
picconv, in a structural sense: there is no upload endpoint at all, so there is no server-side copy, log or retention policy to trust. TinyPNG processes uploads on its servers. Both are legitimate; only one keeps the file on your machine.
